I love love love this set! I bought a small in Cove. It's flowy, light weight (humid island life approved), and so chic! I would say that I could have done size XS (I am 5'6 and 115lbs), but I went for the small and am very happy with it!
Textured, soft material. It has an adjustable string for the waist.
I'm wearing this everywhere. In the house, at the airport, at the beach and at resorts. Im stoked.
