I don't think  so :

• a bikini string cut (if that's what you mean)  ?
   Then the cause wouldn't be simply wearing the bikini for the cut would be symmetrical. Who would be wearing a bikini cutting that deep anyway ? 

A mark left by suddenly pulling / yanking the bikini ?
To recreate such a temporary mark on a texture would be even more weird than a permanent scar.

I stand with my first point of view : someone performed surgery on Jessy G2.
