For reference- 5’3, about 130lbs, 34C, usually a US size 4/small/27 or 28 in denim depending on the brand.
This is such a cute sweater to go with high rise pants. Super soft and warm. In terms of itch: I think it’s actually on the softer side of their sweaters but I also realize I have a pretty high tolerance of fabrics if I like how it looks.
