What to wear to the club?

I'm going to a bar for a friends birthday and the theme is beach attire. We have to wear beach/summer attire unless we want to get charged a $20 cover charge for not wearing summer/beach attire. Girls must wear bikini tops/summer dresses or other summer attire. I personally don't feel like wearing a bikini all night. Do any girls on here have any outfit ideas on what I can wear. Pictures/links are welcome :) Thanks!
