I have so many of these sweaters and just.love them. Perfect for tank top over simple shift dresses or even over a bathing in the evening during summer. This one is acrylic but it has a sheen like it had silk in it. Hand wash. Made to be a bit longer with slis at the sides. Bust measurement is 25" across from underarm to underarm. The length is 26" and the overall sweater is very stretchy. No damage.
