I don’t really care how it looks precisely, so long as its semi-professional and consistent in its style.

I’ve often seen NSFW used as basically just “contains nudity”. You could have a woman in skimpy clothing shaking her everything in a manner clearly trying to evoke sexual thoughts, but because her nipples and genitalia are technically covered, it would get posted as “SFW”.
