For reference- 5’3, about 130lbs, 34C, usually a US size 4/small/27 or 28 in denim depending on the brand.
I sized up to a 6 on these and probably should have gone with an 8 but they sold out. I liked them enough to keep them but wouldn’t say love. Cute detailing on the front and I like the length as a crop. I will probably like them more in a few months, still losing baby weight (:Sezane,size 6,,5’3-5’4 5’3-5’4,Size 6 All Reviews,Sezane
