One thing I like about that genre is that if they're not too close up, there are often non-shy beach babes in the background as well.
I don't have a pic, but I did get to see some covered nudity at West Fest outdoor rock concert the other weekend (as well as some non-covered nudity.) There was a girl in the crowd dancing topless, who had long hair that covered her boobs when she wasn't moving, but bounced around when she was dancing or leaning over to pick up things, which she did a lot.
