I would say that the issue isn't so much including nudity and sexuality as putting them in the wrong damned place. There ain't any reason in the world for an adventurer to be dressed for sex appeal over practicality. It's illogical, and it just looks dumb.
I'm going to take a moment to make a distinction.
Picking on Paizo here,
lots of skin on this cover. However, as I understand it, this woman is the Iconic Sorceress. And while her outfit is impractical, there's no practical reason for a spellcaster to be covering up. Aside from their spell components and magical items, a spellcaster might as well walk around naked - they are penalized for wearing anything heavier than a shirt. And in the life of an adventurer, you're not going to face many things that
can't blow through that shirt like it's tissue paper (hell, those clothes can catch on fire).
Yet. As posted earlier,
this cleric and
this elf rogue however, are dressed for Fighting. No skin, just "Let me at the badguys." It's not necessarily practical (You're going to stab yourself there, elf), but it looks fine.
Going back to the Laura Croft example, some revealing outfits Do make sense. That rogue who's bending and crawling and climbing and dodging can't afford to wear something that would restrict movement or weigh them down. And while some may go the Ninja route (Loose pants, loose shirt), others may go the Bathing Suit route. And let's face it. Some characters
are that damn flamboyant, like
that swashbuckler, who care more about look than utility.
For different reasons, I think Skin Showing is on par with Armor Spikes. Just slapping armor spikes on any suit of armor (or
shoulder pad, arm bracer), or revealing skin on any breastplate just comes off as looking stupid - it's impractical (those armor spikes are going to hurt when you need to stop, drop and roll when on fire, or are going to catch on something as you're crawling through that tunnel). But some armor designs, the spikes
look good, like the Death Knight or something. As such, for some designs, skin makes sense, or at least looks like it "fits"; that
Dervish, whose class is built around sweeping, flowing and dancing with curved baldes, would have an outfit that
looks good sweeping, flowing and dancing with curved blades.
