I looked all over the place for a 38 DD UNDERWIRE tankini top that didn't require my taking out a loan.  I took a chance on a shirred front one, from another company, with no underwire and it makes me look bigger, which I do NOT want, and kind of gives the uniboob appearance.  That's when I went looking on Amazon and found the Sunsets Women's Twist Tankini.  It's very slimming and supportive, and the girls stay in place.  I haven't been swimming in it yet, but I plan to pre-wash the top in my organic lengerie soap, and drip dry before I actually break it out on the beach or pool, based on another reviewer's comment that the top was not color fast.  Sometimes the manufacturer "over dyes" to compensate for some fading that occurs with chlorine and sun. Doesn't hurt to pre-wash.  The top comes down to about mid hip on my swim skirt, it hides a not so fit ab because of the twist construction, the construction in the back is not as form fitting so again it hides a multitude.  Very comfortable, and I'm thinking of buying another in a different color to mix it up a little and have a back up that looks better than the shirred one I bought earlier.
