I took size 36 (US 4). I'm 5'5​,​ 135 lbs​,​ small chest but broad shoulder​,​ small waist but wider hips. İ have the Ralph jacket for the oversized look also took in 36. Christie jacket i probably couldn't wear with chunky knits. Hope this helps! ♥️＜abbr＞Sezane​,​4​,​$225​,​5'5-5'6 5'5-5'6​,​Blazer​,​Coats​/​Jackets​,​French Brands​,​Size 4 All Reviews​,​Sezane​,​Uncategorized＜​/​abbr＞
