If you want to try another one...

Hands down, my favorite one made by Wacoal... they sell it online as well as many major department stores (e.g., Nordstrom, Macy's, Dillard's). My favorite is the Sport Underwire Bra... I know, I know it sounds uncomfortable but it is actually extremely comfortable as the fabric behind the underwires is a single piece so the underwires lay on top of it so you can get the best fit. I used to wear this almost everyday while breastfeeding a few years ago as it provided so much support when just moving/walking around was painful... so obviously it works well for me now for exercise.
