Just a trivial question (not so much

)
the shot of the girls from above, are they topless or not?
I mean if they are, it's hot, if not it's hot but not as much...
Seriously, if they are, it could give us an indication of how far the movie could go into "adults" theme
knowing that Tony is a womanizer, will they tune that side down to go for a larger audience???
(is there a rating officialy announced somewhere?, i remember a that there was talk of a PG-13??)
(not being familiar with US rating, i don't know if showing boobs is pg-13 or not?, i suppose not

)
