Halloween costume

Ok so I have a party on the 28th to go to and my FH says I should go as Elvira because in his words ... I have the ta-ta's for it. so I might actually do it because the costume is not expensive .... but now I need a good bra ... any sugestions on any make or style.... that also is not that expensive? I'm on a budget here

LOL cute idea- a great pushup would be Fredericks of Hollywood X bra. I dont know if that is the name but it has a little X in the middle of the bra.
