It can be, no doubt. Erotica is more often than not an image or sound that forces you to fire up your imagination as to what lies beneath, but not seeing it. 

OTOH, it all depends on how it gets presented IMHO. A lot of the outfits presented in the RMP don't quite cut it - it's like they're only showing it off just for the sake of showing it off; there's no 'reason' (for severe lack of a better term) for it to be sitting there exposed... and often calls to mind phrases like: "Daamn, girl - didn't anyone tell you that you shouldn't wash that armor on the 'hot' setting?"  That, or it's like someone threw a transmap on a top and got... that.

Then there's the "damnit, the physics are just plain wrong here" angle. Not to nitpick on you personally, but the image you showed does illustrate this. Forget the apparent age of the character for a second, and take a look at the cloth: Worn on a chest with breasts, the cloth between them should be stretched tight, at a straight (or near-straight) line between them, due to the apparent tension that the cloth has to undergo just to hold everything in there (since there's nothing that would otherwise hold it up, such as straps and etc).
