I absolutely love this Athleta Twister Bikini top! Not only is it super comfortable but I feel so supported in it.
The twist front gives it a stylish look so you do not look like you are wearing a plain sports bra.The adjustable straps in the back can be worn straight or with an x-back (I like the x-back). It also has an adjustable three-look hook-and-eye rear closure for an even more supportive feel. I was able to run and play with my kids with out fear of popping out or having to constantly re-adjust.
The only thing that I do not like about this swim suit top is the removable pads in the cup area. They are for for extra coverage and work great, but when you wash the swim suit they get all bunched and twisted up; fixing them can be a real pain.
This top is on the higher end of swim suit tops, at $56, but for the support and comfort worth it.
