Definitely one [piece once you hit 60!
Even though I am slim, gravity calls after about 40-50!
I like two piece on young pe3ople as they have beautiful firm bodies, but once things start to drop and you do not have that svelte figure any more, definitely one piece is more flattering.
I wear a rashie because I'm chalky pale and burn so quickly. I've never really liked bikinis. I was too insecure about my body when I was a teen/in my early twenties, and now I have finally learned to love my body I just don't like having that much skin exposed to the sun. Besides, they are not great for beach swimming because there is the worry that they'll come off in the surf.
