Continuity mistake: In the very last scene just after Max Lomax exits, the band starts playing again. You can hear drums playing however Roxy is dancing with her boyfriend and there's no-one at the drum kit.
Continuity mistake: When one of the girls gets the blue drink all over her top we see that a lot of her white shirt has been covered in it, but when she goes into the restroom she doesn't have as much of the drink on her as before.
Continuity mistake: During the whole car chase scene when the girls are being chased by Max Lomax, Jane is driving the taxi and there is a cheetah skin cover on the steering wheel and as they keep changing shots it disappears then reappears.
Continuity mistake: When Jane and Roxy are being chased in the taxi by Max, the scenery behind them shows a sidewalk to the right of the car, however Max turns up on that side and suddenly there is another lane.
Continuity mistake: When Roxy climbs out the limo's sunroof she is wearing green underwear, but later when she slides off the window cleaner's conveyor into the dumpster the white underwear is visible under the towel, even though she is supposed to be naked.
Continuity mistake: When Roxy fights the fake Chinese guy with her drumsticks in the subway station, Jane and Roxy end the fight by grabbing his coat/jacket and pulling it over his head, then shoving him into a subway car. When they first shove him, the jacket is over his head. When he is stumbling in, it is suddenly nice and neat, down in its proper position. But the in the next shot of him hitting the seats, it's back over his head as he struggles with it.
Continuity mistake: Roxy's hair's waviness varies throughout the entire movie until it is finally completely straightened when she comes out of the House of Bling.
Continuity mistake: In the scene when the girls are in that guys apartment we see that the chip is blue, but then when the guy sees his dog eat the chip he calls it a green chip.
Continuity mistake: In the scene right after Jane and Roxy escape from Lomax and they are still in the taxi talking to each other. Roxy's hair goes from tucked behind her ears to in front of her ears between shots.
Continuity mistake: When the fake Chinese guy calls Jane on her mobile in the hotel room she calls for Roxy. If you then look at Roxy's hair you'll see its position change several times. First over her ear, then behind her ear then, over her ear, etc.
Chosen answer: Before the girls go to the stall where the "I heart New York" shirts are, they broke into an apartment and Jane could have left her clothes in the bathroom when she was taking her shower, and Roxy could have left her clothes somewhere else around the hotel room. As for their towels and robe, they could have disposed of them in a bin or left them in the cubicles etc...
