Tara Grinna bathing suit cover up, kaftan with tie. OS The ease and flowing nature of this cover-up is why it is so popular amongst Tara Grinna's most loyal clients. Slips over the head and falls gently to conceal just enough to be able to go from poolside to lunch with ease. The fabric is a translucent cover-up fabric but can be worn over a black white or nude body dress to create a resort wear dress that can go from day to evening.
