un-sept Sleeveless Dress Size: 38 Length: 100 cm Zipper on the left underarm Outer: 100% Cotton Lining: 62% Polyester, 38% Composite Fiber (Polyester) The care label indicates "Do not hand wash," but I hand-washed it with a delicate detergent, and it held its shape perfectly. It's a very cool and comfortable dress.
