Florence rocked her bikini last January while enjoying a day off in Rio De Janiero, Brazil. Her high-waisted swimwear was completed with a stylish red swimming cap.

Ke$ha wore this two-piece while on tour in Australia in March 2011. The more conservative attire is a stark contrast from what we're usually used to seeing her wear!

What doesn't Taylor look good in?! She rocked an adorable and modest polka-dot bikini while enjoying a vacation in the Bahamas in 2010.
