i think its ambiguous. the original design probably has clothes. Then when they put in on the system, someone probably thought it was "cool" to have it the way it is. If you look one second she looks topless, if you look again you swear that you see something that resembles clothing.

Regardless. She just looks weird, The stance is so odd looking. The proportions are way off. Who ever approved this design concept apparently liked it and has completely different tastes then most of us.
