Bought a large. Love it. It's a knit sweater so you'll need to wear something underneath for warmth. For reference in 5' 6", pear shaped, 34c, 30 waist, 40 hips, 150lbs.

I was literally sitting outside with the fam eating our Thanksgiving dinner let me tell you i was warm the whole night and everyone was saying how cold it was and i never complained because i was good 🙌🏼💯
