Alterations tutorial: how to re-size an oversized blouse


Cabochon print blouse and pink pencil skirt, both from Savers Thrift Store


Thrifted blouse & skirt, DIY altered, BR swing jacket, Christian Louboutin pumps
I headed to the thrift store for inspiration recently – my visits there are hit or miss, but this time I skipped out with two pieces to experiment with. This blouse caught my attention right away, despite the dowdy silhouette and oversized fit. I like the vintage flair given off by the pink cabochon stones with antique gold backing, and the fabric-covered buttons. It can be pajama-like when worn alone, but adds interest when peeking out from underneath layers.

This skirt, labeled a size 5-6, was roomy in the hips but a perfect fit at the waistband (calling for easy alterations). Below are the alterations I performed on both…

I highly recommend washing and drying pre-owned items before starting any alterations. This is not only for sanitation purposes, but also prevents shrink-prone items from becoming too small after alterations.

Steps 1 through 3: The first issue I addressed on this blouse were the too-wide shoulders. In the past, I meticulously detached shoulders and re-cut the armhole openings. This was very hard to do and took me days as a non-skilled sewer, plus the outcome was far from perfect.

This time, I decided to experiment with a shortcut. I added ruching (gathered-up fabric) to the top of the shoulders, which effectively narrowed the shoulder width and shortened the sleeves. Basic ruching is quick, easy and useful. Details on how to add ruching via hand-sewing:

Step 4: Next, I slimmed down the upper torso and sleeves, up to the cuff opening.

Step 5: I then removed the waist darts on this blouse so that it would have a more flowy fit for wearing both tucked-in and un-tucked. Ironing throughout is the last step.

As for the skirt, I simply slimmed down both sides from the interior, starting right below the waist band:

    Love it! I'm about to try some DIY alterations.

    I ran across this top on

    I know it's probably not your style, but it's on big sale and runs really small, according to reviewers. Just thought some other tiny readers might like to know!

    These alterations are amazing! You chose so wisely!! If something doesn't fit right away, I'm most likely not willing to buy it. Maybe except if it's too long. You've got a great eye! I love how you changed the blouse. The skirt is pretty, too. I love bold colors.

    Can't even believe that you bought those at a thrift store because they look like designer clothes. Crazy amazing outfit.

    Hi Jean,

    Love your DIY sewing/alteration projects! As a petite person with very little knowledge of sewing, I have a question: When you slim the sleeves and sides of the shirt and skirt, do you cut off the excess fabric or leave it?

    Thanks! ~Sandy

    I love this outfit and I'm so impressed that you altered it yourself! It looks really expensive; I can't believe it was under $10… ALSO I LOVE YOUR HAIR!!! I am Asian and it's really hard to give my hair texture and volume. What products do you use? I wish I could get your look! <3 your blog!

    Loving the thrift finds slimmed down!! The top is gorgeous! It makes it so much more special when you know it is so unique and that you made it what it is! And a super low price always brings a smile to my face!! 🙂

    Wow, that's incredible. I love how you alter your own clothes, but I think I might even go further and take some classes on tailoring. I love sewing, but I'm quite terrible at it.

    You are getting so good at sewing!

    I love that skirt, what a find! Thrift stores are always hit or miss with me too but when I do find something I love it's so exciting!

    PS your hair looks great in these pics!

    Lovely skirt!  I love thrifting!  Over the last few months, i found some great things: Burberry+Dior white dress shirt, Alice+Olivia chunky knit cardigan, MaxAzria pencil skirt, Pinkyotto dress, some silk blouses, Theory sweater and dress pants, a real pair of Chanel jeans (unfortunately not my size, but my sister's).  All of them are around $6, some $3 on 50%off day at Goodwill, and stains.  Most of them are my size, and some needed minor alterations that I can do by hand.  I don't know how to use a sewing machine like you…Great blog!

    Edit: And no stains. (sorry)

    Hi Ruby – thank you so much, but I don't use any products on my hair. I sleep with it in a bun to get some waves – sometimes it looks terrible like a nest, sometimes it works!

  • Reply PetiteAsianGirl August 28, 2012 at 9:20 pm

    If there is enough excess, yes I do cut it off but you need to make sure to either re-serge the edges (and most people do not have a serger machine), or fold the raw edges under and stitch to keep them from fraying. With this skirt the excess material was bulky so I did trim it off and foldled under the raw edges, them stitched to secure them.

    Thank you! I use a 10 year old super basic brother machine which is no longer made, but this is the closest one available now:

    THanks for sharing!

    Hello – I use a sewing machine for almost everything except blind stitches (where you don't want the stitches to be visible from the outside) or delicate fabrics. I also used hand sewing for the ruching here, but very rarely do so elsewhere.

  • Reply PetiteAsianGirl August 28, 2012 at 9:23 pm

    I've looked around because many ladies have asked, and I think one of the best values out there is this basic brother machine: It's extremely similar to mine, and mine has lasted me well over a century so I think Brother machines are pretty durable.

    Thank you so much for your kind words!

    Hi there – I took my class in China : ) I'm sorry I can't be of more help on class options offered here in the states, but I was thinking Michaels or JoAnns.

  • Reply PetiteAsianGirl August 28, 2012 at 9:25 pm

    Hi Evelyn – I use a machine for everything else. It's much faster and the stitching is infinitely sturdier than my own hand-sewing.

    You can ask the ladies who volunteer at the Purse Forum to help authenticate under the Louboutin authentication thread. Otherwise, it's just up to your judgement unfortunately, and there are many fakes out there.

    Thanks! It's a really old, discontinued lipstick from Clinique – color is called soft bloom soft shine. I bought it ten years ago and picked up another one on eBay.

    I got a YSL scarf for three bucks!!! I also found an authentic Louis bucket bag for $30, I know it was over $10 but it was an amazing find!

    You're a genius! Question–not sure what you mean by "slimming" the shirt (and skirt) and the stitch lines. Did you CUT OFF fabric up the stitch line or just sew the inside?

    I just did the shoulder ruching. Thank you for the tip! You just saved my sweatshirt blazer that has been sitting in my closet for months!!

    Hey! I just came across your blog yesterday and now I am a big fan! I love when you show the beginning and ending products because it's easy to feel disheartened when pieces don't fit or if you can't figure out how to pair them, but you show it's all about vision! 🙂
