Whole lotta shakin' goin on
I have heard of people wearing two sports bras to keep the gals under control. I tried one regular underwire with a sports bra over the top once, and that worked out pretty nicely. Got support and suppression, but helped avoid the total uniboob thing. And yep, the beautiful spandex pants, or control undies for the tummy. Good luck and have fun with the softball season!
