My wife is my dive partner. People look pretty much the same in a wetsuit; most women don't look significantly different from most men when squeezed into a neoprene outfit. It's why we use bright colors to identify ourselves in the water.
The sexy looking vacation advertisements that show a bouncing babe in a bikini snorkeling in crystal blue tropical water are terribly misleading. Yes, tropical water is fantastically clear. But any serious diver will tell you that diving without skin protection (at least a 1mil wetsuit or a 'shorty') is a great way to get stung or scraped up. And any serious snorkeler will tell you that spending any amount of time in the water requires protection from the sun - a thin wetsuit again.
