i cant give her her dress cause she only talks about the booze and the producer either fucks me at day or that other girl at night
Okay, so there might be some confusion here...
Which dancer costume do you have? There's 2, one you can wear that is white (bought from the shop) and Carla's which is a super skimpy string bikini thing for the quest.
If you don't have the right one, the quest will not progress.
Also, you can only give the producer on the 3rd floor the camera at night, I think. If he's already having sex with people, then you already finished that stage, and you're probably missing something else in that sequence of events. Screenshots of what things look like (inventory, what characters are doing, etc.) would help.
