Is it real?

The way I usually spot the really good 3d renders is look how fabric is behaving.  Unless that was some seriously stiff fabric, it should lie over her fingers.  There is also some odd fitment things going on right under her boobs.  The fabric is still trying to conform to her breasts when there is either no tension (the bathing suit should be looser lower) or she adding tension (the suit should try to wrap under the breast, it would be taut between boob and lower).

Darn close to spot though...
