I have several, all types. One was a mistake. It's way too revealing for an ordinary beach. One is a bit see through when its wet. My favourite is a red and white normal bikini. I wear it all summer when I'm on the beach.
Just one. Your basic black triangle top with halter ties in back and around the neck; high-legged bottom with ties on the sides. And no padding! Why is it so hard to find bras and bikini tops without padding?
