here are a few of my favorites i found when searching the web...
SPANX, (a womans best friend! if its not, then you need to make it!), has come out with a swimwear line and i LOVE it! who wouldn't want tummy controlling swimwear? these were some of my favs from their website:
love the colorblocking on this one. makes it look sorta retro.
i'm always a fan of jcrew's swim collection. they're simple, classic, and flattering (most of the time). this was my favorite this year...
the ruffles will conceal and imperfections your wanting to hide in the tummy. it has a tie around the waist to create a figure. its strapless, so you still get that perfect tanline-less tan. love it!
lets not forget you need the perfect cover-up too. this is especially true when you're at the beach. i found this one on Anthropologie's website.
such a pretty pink, and love that shimmery gold detail. this would be perfect to hit the beach in, but can wear to a beach party that night.
i also found a great website that has great tips on how to find the best fit for your body when it comes to swimwear. they have TONS of swimsuits to choose from, you are bound to find something you like here.
happy swimsuit shopping, and good luck!
