TSandM:Yeah, does anybody know of a sports bra made of polypro or microfiber? As I requested that my male buddies avert their eyes yesterday so I could pull off my sopping wet shirt (wrist seal problems) it occurred to me that a nice sports bra would avoid the problem. But they're all cotton, which is not a good fabric to have on when you get wet.
A nice black bra and panty set that looks like a bathing suit would give me a lot of clothes-changing options for sites with no facilities!
Check your local sporting goods store or LDS for Aeroskins swim/dive wear. I think they make some thing in Polyfin like what you described.
