100% cotton Neuflora Plymouth Cardigan Only tried it on. Pit-to-pit measures about 21 inches (for a slightly looser fit). Size M. For reference: I‘m 5‘5“ and about 145 lbs; the medium fits great. Super cute and a lovely staple. I just bought this on a whim before they sold out again but now my return window is closed and I am not sure if I like it for myself as much as I should. Hence, decided to sell and get a different colored cardigan. Clean, non-smoking, pet-and fragrance-free home.
