I need to buy one piece swimsuit for vacation to puerto vallarta in January?

any suggestions for where to buy online bathing suits? I am almost 50 years old, my body shape is o.k. I need something comfortable and pretty, a slimming one piece bathing suit. I am going on a dream vacation to mexico!

uh there is victoria's secret or you can go to aol and search for some in their shopping section, have fun! xoxo
