So I know the Website has a sizing chart, but I am solidly between S and XS for a cardigan. Can anyone help. I would like it to be slim, not too tight, and going down not more than an inch below my belt. Here are my stats: Height 5'6" Weight: 120 lbs. Waist: 28-30 Sleeves: 31-2 Chest: 34-36 I dont have measurements for my shoulders, but I am not too broad. I am a small, skinny person. Can anyone help me? Thanks.
