I used to be a bikini woman, but I am in love with the retro one-pieces this year. These UO swimsuits are amazing! Luckily I don't need my swimsuit until the end of the year, so I will keep my eye out for markdowns.
I'm only 21, so I'll definitely be rocking a bikini on the water, but I might have to purchase a one-piece for poolside lounging! For a one-piece, I love this adorable Pinstripe Seersucker Shirred Underwire Tank from J.Crew: http://www.jcrew.com/catalog/product.jhtml?id=prod94298161&catId=cat303403.
