I've never had a problem with having no drawstring. Short of high diving and possibly boom netting (is that still a thing?) they should be fine.
I have some Thinskinz suits. Wonderfully soft and thin but go real dark in potential transparency is an issue. I have chocolate brown (fully opaque) and burnt orange (can tell when wet but not too obvious against my Caucasian skin). Of course Skinz change their colours continuously. Since they're unlined, there's a fair bit of detail showing.

My new suit is black, but on the sheer side.
It does have a small double layer over the cock and balls, so that should reduce the detail.
