I love your recommendations on Corporette. Up to a swimsuit challenge? I'm going on a beach vacation (yay!) which requires swimsuit shopping (boo!) I'm looking for something cute and on-trend but practical enough to play with my kids. I'm tall so I prefer tankinis (no bikinis for me since the kids.) Relevant facts: 5'10" so most 1-pieces are too short (and "long torso" suits usually look like grandma-wear) I'm generally slim but with post-baby pooch and muffin top. Super self-conscious about this. B/C cup I'd normally go for something like this: J-Crew Pintuck Bandeau Tankini, but I need to find something that won't fall down or (maybe even worse) fly/float up to reveal my mid-section when I'm playing and swimming. I also like prints but it seems like the more updatedl prints are all in bikinis - double boo. Price up to $200 - I'm desperate! Thanks!

Its still kind of cold, rainy and gross outside here in lovely New England, but the first signs of summer are my ask box!  So, I have a few favorite places to look for swim suits, Lands End and Athleta.  So I'll point you to a few favorites there.  I think these particular stores will be good matches for you because they sell more athletic suits, meaning they will be less prone to pulling up or otherwise being a pain in the but to swim in. So let's do this thing.  
Women's Regular Beach Living Graphic Wave V-Neck Tankini Top from Land's End ($23.40 - comes in a tall size also - you of course can pick the bottom you like.)
Women's Long Beach Living Bardot Floral Scoopneck One Piece Swimsuit from Land's End ($50.40 - I wanted to give you at least one cute long one-piece option - and for my bigger busted readers, this comes in up to DD.)
Women's Regular Shape & Enhance Floral Surplice Tankini Top ($59.40 - I like this one and it has some shaping built in that will help make it more flattering.)
Land's End has several other long suits that you should check out, plus, I like this zip front cover up which might be nice for hanging out on the beach for long periods with your kids and then leaving to head back to your hotel or whatever.
Bombay Bra Cup Twistini Tankini at Athleta ($76 - comes in two colors and two designs, has built in cup in a variety of sizes, and comes in tall size as well.)
Sara Bra Cup Halter Tankini at Athleta ($72 - this is quite like the one you like from J-crew, but it comes in a tall size and with a built in cup and with a variety of colors.)
Space Dye Kata One Piece at Athleta ($79 - another tall sized one-piece and this one is down right sexy.  I like it!)
Okay - those are just a smattering of my favorites at Athleta - you should check it out.  I love their suits.

So these are my favorites at my two favorite swimsuit stores.  Some other places to check out are REI, LL Bean, and Target.  Speedo, the competitive swim suit brand, also sells some tankinis that are pretty good and would likely not ride up if you want to check those out as well.

Hope this helps!  Have a great vacation - and hope the swim suit problems fade into the background of an otherwise awesome trip.  :-)
