• DIY Alteration Tutorial: Sewing/Resizing a Long Sleeve Blouse

    Per your requests, below are the steps I took to completely re-size a long-sleeve blouse. I’m sure it’s not the professional way to do it (readers – please share any tips or corrections), but I just followed logical guesses. The text in red indicates when to actually sew.

    1. Find a basic blouse that already fits you the way you want the new one to fit. This can be your “pattern.” Turn the too-big blouse inside-out, and lay the “pattern” blouse on top of it, aligning the shoulders.

    2. Using fabric chalk (you can buy these at sewing/craft stores or on eBay), mark how much to take in on each side of the torso. Start at the bottom of the armpit and go all the way down to the hem. Repeat on both sides and measure to make sure both sides are equal. Stitch along both sides of the torso, exactly where marked.

    At this point, turn the too-big blouse rightside-out and try it on (yes, the shoulders and sleeves will be awkward since only the torso has been taken in). Check if the torso width is per your liking and also check to make sure the armhole width isn’t too tight. Undo the stitches and re-sew, if adjustments are necessary.

    3. Turn the blouse inside-out again. Use chalk and mark the new shoulder width on the too-big blouse. Trace the curve of the new armhole from the top (where the two black arrows are pointing) all the way down to the bottom of the new armhole, which is where we started marking the dotted line in step #2. Note: the armhole curvature on the front and back are not the same. Using chalk, try to mirror the curve on the “pattern” shirt to the best of your ability.

    4. Using tiny scissors, snip the original stitching that attached the sleeves to the torso. Immediately mark both sleeves with chalk (the shirt should still be inside-out) to make sure we re-attach the proper sleeve to the proper side. I use numbers to make it extra clear.

    5. Next, trim the armholes down to the new curved holes that we drew in step # 3. When cutting off excess fabric, make sure to leave a 1 cm margin outside of the line you traced. In this step, also make sure to trim ONLY the torso piece.
    dotshirtresize3
    6. Now move onto trimming the sleeves. Compare the removed sleeve against the “pattern” blouse sleeve and mark the new length. Keeping the original curvature of the sleeve, trim the length down, making sure to leave a 1 cm margin again outside of the chalk line.

    **If you have a blouse that fits perfectly in the shoulders/torso but the sleeves are too long, one option is to shorten the sleeves from the shoulders. I know some tailors do this for sleeves that have cuffs or other details at the hand opening that are hard to alter.**
    dotshirtresize4
    7. Re-position the trimmed sleeve against the trimmed armhole and tack in place using a pin at the top of the shoulder seam. Make sure that the numbers we noted in step #4 match up. At this point, the entire shirt should still be facing inside-out.
    dotshirtresize5
    8. From the armhole, reach your arm through the sleeve piece only, and turn it rightside-out, but while keeping it in place. This part is a little tricky to describe. So, if we are looking at both pieces on the floor in step 7, reach your right arm into the sleeve, grab the sleeve cuff, and pull it through back out towards the right. This entire time, the small pin at the top of the shoulder should still be in place.
    dotshirtresize6
    9. Place the sleeve (now rightside-up) into the armhole, making sure the edges of the armhole is aligned with the sleeve hole. The torso should now still be inside out. and the pin should still be in place.
    dotshirtresize7
    10. Holding the sleeve in place with the armhole, stitch along the edge of the armhole to attach both pieces. Per a tip from sewing expert Sew Petite Gal, start at the top of the shoulder (where our little pin is) and stitch down one side, and then go back up to the top of the shoulder and stitch down the other side. This way, if your sleeve piece is not a perfectly-cut fit for the armhole, then any mismatch will occur at the armpit and be more easily concealed.
    dotshirtresize8
    11. After the sleeve gets attached, turn the entire blouse to the right side and try it on, making sure that no stitching was accidentally done on the visible outside. All stitching should be done on the inside-facing side.

    If the armhole is comfortable and the sleeve length fits right, turn the entire blouse inside out again to make final adjustments. If the sleeves are too wide, trace a new sleeve width using the “pattern.” Stitch along the new sleeve width, continuing your stitch to the armpit, and down the upper torso slightly just the clean up that junction. Fade your stitch line in with the original torso stitches we did in step #2.
    dotshirtresize9
    You’re done! Turn the entire blouse rightside-out again and try it on. If all is well, iron along all of the new stitches we made. If you have a serger machine, lock the edges of the raw seams to prevent fraying. If you don’t, I use the zig zag stitching on my basic stitch machine to do a cursory locking of the raw edges.

    12. Optional:< /i> The last thing I did was remove a frilly edge running along the front buttons. I thought the blouse would look less childish and more classic without this detail.

    For those who are interested in learning how to sew, I highly recommend taking a beginner’s course and starting with an affordable machine like this Brother Basic Stitch one. I took a class as a teen in China, where I learned the basics of stitching and using a sewing machine. If anyone has recommendations for classes in the U.S. or tips on how to begin, please share in the comments!

      Ahhh, so great!! <3 Love the ruffles, hihi!

      ♥♥♥

    • Denysia Yu September 26, 2012 at 12:04 am

      This shirt looks super cute with the added ruffles! 🙂

    • Caroline September 26, 2012 at 12:06 am

      Thanks for the tutorial! FYI, places like Joann's Fabrics offer sewing classes often, as do independent fabric stores and sewing machine shops. I would start there, and most Indy places also offer private lessons as well.

    • paisleyprints September 26, 2012 at 12:14 am

      i love how you manage to alter these things to fit. i'm from Singapore and you might want to check out G2000 or the many online blogshops we have here, petite is the norm, you might enjoy being able to fit into a regular S here.

    • Tegan September 26, 2012 at 12:26 am

      So helpful!! Thanks for posting this. I'm tired of belting my too-big blouses!

    • Megan September 26, 2012 at 12:44 am

      Thanks so much for the tutorial, Jean! I have a silk Ann Taylor blouse from the thrift store that I want to slim down. I'm not an expert at sewing (at all), but I'm going to give this a try!

    • Elizabeth September 26, 2012 at 1:43 am

      Does any one know of any online lessons on basic sewing?

    • Janet Cheung September 26, 2012 at 3:41 am

      You are multi talented, Jean!
      Can you still speak Chinese? Cantonese or Mandarin?

    • mingming September 26, 2012 at 5:32 am

      Great tutorial Jean! Some good places to learn sewing:

      Locally:
      -Check your local community college or county adult/community education courses for sewing class listings
      -Some Joann fabrics offer basic sewing classes as well
      -If you have a local fabric store it can sometimes offer classes
      -Vendors for sewing machines will often have courses on using the machines

      Online:
      -Craftsy is a place that offers online sewing classes with videos and you can ask instructors questions; most of their teachers are fairly well-known in the sewing world

    • Fashion Blawger September 26, 2012 at 6:51 am

      Awesome tutorial! I am inspired by your transformation. I am interested in trying this with my J Crew silk blouses. Any experience/suggestions with sewing silk?

      Thanks for sharing this info! 🙂

    • Helen Ricky September 26, 2012 at 7:42 am

      The main reason why I start reading your blog (and love it!) is that you're doing with all these clothes, converting them to masterpieces.

    • Planned Style September 26, 2012 at 9:21 am

      I love it when you do this DIY Tutorial posting. It’s inspiring me to do the same thing, not that I know how, but it’s very motivating. Thank you. I can't wait until I have a sewing machine.

    • Olivia September 26, 2012 at 9:54 am

      Thanks Jean!!

    • Anonymous September 26, 2012 at 10:08 am

      Hi Jean, amazing work! I see you fold the raw edges in, instead of hemming them. Does that make the seams thicker/stiffer than otherwise?

    • Always Maylee September 26, 2012 at 11:47 am

      WOW. I'm completely amazed. I really want to learn how to sew and be able to do some DIYs like this! Thanks for the tutorial and would really love to hear of any ideas on those beginner's courses! 🙂

      xo, Yi-chia

    • Sheila September 26, 2012 at 12:15 pm

      Amazing job!!!!! I wish I can be talented and know how to sew like you! I can save myself a ton of money! -_- Love the after outfit alot! That wool skirt def looks better as a shorter mini. 🙂

      xo – Sheila

    • Grace September 26, 2012 at 12:46 pm

      That is a lot of work Jean, my hat off to you. I have started sewing lessons through a website – and this is for readers who might like an affordable online sewing class. I take it from Craftsy.com and started with the Couture class because I already know how to sew. The lessons are about 45mins to an hour long and if you sign up, they will alert you when classes are at $19.99, which is what I paid for most of my other classes. You get to review your lessons again and again and they have patterns for download so you can follow the class.

      Another great tutorial. I can do this!!

    • Dzung September 26, 2012 at 2:38 pm

      i'm so inspired!! you are so brave to do this to your clothes! i would butcher it. completely. but maybe i should buy a few just pieces to practice. This is brilliant!! love your blog too! 🙂

    • Lisa September 26, 2012 at 3:06 pm

      Stuart Weitzman kids boots… that is SUCH a great idea! 🙂 Thank you!! May I ask what size you purchased? I think we have similar sized feet (I am usually a size 5 at Aldo).

    • Anonymous September 26, 2012 at 3:52 pm

      So glad to hear you are still blogging.

    • IchigoBunnie September 26, 2012 at 5:13 pm

      wow such a good idea! and ive always wondered how to alter a shirt. your shirt looks great now, including that skirt!

    • Abby September 26, 2012 at 5:19 pm

      I have been dying to try this myself for years, but I haven't had the courage. I've got the pics now, step by step…I have no excuse to not do it!

    • Unknown September 26, 2012 at 5:57 pm

      Wow! that is a lot work almost like making a new blouse on its own! Amazing job!

    • Sandra September 26, 2012 at 6:14 pm

      Ordered these boots myself this morning after reading your post! Your blog is a great resource, not just for petites, thanks you!

    • SewPetiteGal September 26, 2012 at 8:20 pm

      You did such a wonderful job here! I've never done a complete blouse overhaul like this before so I definitely learned something here. I stand by my opinion that sewing from scratch is easier. I have a great deal of admiration for your skills here so I had to laugh when you referred to me as an "expert". 😀

    • Petite Therapy September 26, 2012 at 10:35 pm

      Incredible! That's exactly what I want to do with clothes in the future. I'm going to start sewing lessons on Saturday. Maybe that'll help me understand what you actually did! I'm going to a small studio in Brooklyn and also to The Sewing Studio in midtown Manhattan.

    • Jane September 27, 2012 at 7:33 am

      I've been a sewer for years. One tip: IRON the seams as you're sewing. The crisp look of an ironed seam makes things look much more professional and clean.

    • lin September 27, 2012 at 8:48 am

      thanks for sharing how you slimmed the shirt. it turned out great. i'm planning on purchasing a sewing machine so i can do some of my own alterations too. you've inspired me with all these DIY tutorials. 😉

    • s September 27, 2012 at 9:26 pm

      love the dots! xO!

      Hi Lisa! I'm a 5 too and usually a 3.5 kids. Got a 4 to try in the boots.

    • le th September 28, 2012 at 5:39 am

      Dear Jean, I need a bag to go to work. And I have to choose between edie and longchamp planètes tote, so could you give me some advices? I'm so confuse. Thank you!!!

    • Marmander September 28, 2012 at 10:15 am

      Thanks Jean for such a great post. I'm inspired to start altering my clothes too. And your posts are so informative. I had a question regarding your Brother sewing machine. Would it be good for hemming denim?

    • Delusions of Grandeur September 28, 2012 at 1:19 pm

      Jean, although I don't post often, I'm a long time reader and had to pipe in and say thank you for this tutorial! I'm petite as well and need alterations all the time – I recently bought a sewing machine and am teaching myself in the hopes of doing my own alterations, DIY, and maybe even eventually sewing from scratch! Keep these coming and have a great weekend!

    • Bonnie September 28, 2012 at 2:02 pm

      hi jean! what sewing machine do you use?

    • Midori September 28, 2012 at 6:14 pm

      i love your alterations posts!

    • Lisa September 28, 2012 at 8:10 pm

      Thanks for your reply. Can't wait to see your review of them!

    • Theresa September 28, 2012 at 11:31 pm

      Thanks for the great tutorial! Also, I like your shopping posts, but I actually love these DIY posts much more. Other fashion bloggers out there who do this kind of thing don't tend to get the classy, expensive-looking results you do, so I love coming to your blog and finding a valuable post on upcycling clothes in a classy way. Please keep it up! 🙂

    • Ana-Maria Marila October 2, 2012 at 10:36 am

      Thank you very much for posting this! it will really help me, since you show here some aspects I never even considered neccessary, but now I see they really are! please do post more alterations for vintage clothing! they are very helpful!
