I love the design and feel of the double-up tankinis. I have a toddler, and I like feeling like I'm not going to fall out of my suit when playing with him in the pool.  Usually, the double-up design is considerably supportive with good coverage.

This suit follows that design, but it didn't fit me worth beans.
I thought that MAYBE I could get away with buying a suit in a general size and not a specific bra size.
Silly me.
I tried an XL, and the ribcage was way too wide but the cups were too small (maybe equivalent to a D cup ... MAYBE, but I measure at a 32 G), so there was no support or whatsoever. The elastic band around the ribs was just way too big to offer any support.  I'll go back to paying an arm-and-a-leg for bra-sized suits.

I was disappointed it didn't fit because it is a very cute suit and design and the quality seemed decent.
If you can usually buy swimsuits in a tee shirt size, this suit would be great.
If you find you need to buy suits in bra sizes, this will not fit well.
