Left: Petite Pencil Jean w/ 31" inseam ($79) Right: Legging Jean w/ 28" inseam ($29)
Holy moly! J.Brand is on Hautelook (invite) today in various lengths, cuts (skinny, boot cut, wide leg), and washes, and I couldn't believe my eyes when I saw the large selection for sz 22. I didn't even know this size existed - it must be equivalent to a 0000P? I snagged myself the legging jeans (ended up getting 23 and 24 to try). Shipping was about $8. If you're petite, look for lengths that appear cropped on the models, and check inseam measurements. I typically pay $10 for a regular hem, and $15-20 to keep the original hem on jeans.
Found cell phone pics of the sz 24 legging jean. Looks like waist & hips definitely fit me - just needed a hem!
