Don't I see a frilly little 'skirt' thing?
This is why black is the traditional color, everything blends.
It would be more revealing if it were any other color, well maybe a mud brown color would be nice...er' appropriate.
I have even a better idea where we could combine a traditional swimsuit and the bhurka head piece so no one could see who you are wearing a bathing suit. You could hide your identity!! LIKE BATMAN!
