For reference- 5’3​,​ about 130lbs​,​ 34C​,​ usually a US size 4​/​small​/​27 or 28 in denim depending on the brand. Also really enjoying this piece​,​ especially the color. I first got the Amiel in the charcoal gray color and tried both the S and XS. I prefer the XS on me​,​ the small would look a bit too oversized. Both very comfy​,​ versatile pieces.＜abbr＞Sezane​,​size XS​,​​,​5'3-5'4 5'3-5'4​,​Size XS All Reviews​,​Sezane＜​/​abbr＞
