Bah! I wear a bikini and I'm 41!!! I say go for it. I bet you'll look fantastic!
Last year, when we went to Cuba, I went to Bikini Village and bought a brand new, beautiful black bikini. It cost me $70. Third day we were there, the clasp on the top broke, exposing me to the entire pool bar area. Ain't that grand? So I went to the little store on the resort and paid $12 for a new blue and white bikini that my SO said looked much better on me anyway.
