Very Comfortable and light Material
Color: White, Size: Large, Color: White, Size: Large
Bought this outfit for our Cruise for White Hot Night.
Light, comfortable and so very stylish. Fabric is on the light side so recommend a neutral undergarment.
Pants are a little on the loose side, shirt is true to size. Will really shrink a whole size if put in dryer.
