Here's how I look at it: if your boss (or HR representative) walks by and sees that picture, will they admire it or scream about sexual harassment lawsuits? Putting pasties on breasts isn't really covering anything (it just looks like the nipples are discolored), nor is a thong (that's just butt floss). If it has enough material to make a decent bikini, then it's not nudity. If you need a magnifying glass to find the material, then it's nudity. Personal opinion: I'm stringent on the nudity flag, and I think there's enough there to be a non-nude pic. Cheers!
