Washed but never worn (hence couldn’t return). Not sure what the material is (maybe polyester) but it’s buttery soft! Very cozy and stretchy knit sweater, the color is classy and the design is relaxed. Size US 4. It can fit people who wear xs-large, 2/4/6/8, as is oversized and super elastic. The pants are 1-2 inches too long for me (I’m short, 5’3). So if you’re taller then please take them!
