As a wider hipped and larger-than-average-gluteal woman, I have issues with two-piece triathlon suits as the top rides up around my rib cage. As a momma of five, this isn’t a pretty sight nor is it comfortable. I had snaps sewn into the hip bone area on the front, and slightly higher up on the back to allow for bending forward on the bike.
I opt for two-piece suits for multiple reasons (bathroom, chamois choices, and vanity). I am a hard-core advocate of the Coeur tri shorts but want to be able to change out tops.
I snagged the snaps at Michaels for about $4.
You can see it worn here with no issues:
I watched many women lean forward on the bike, their tops ride up and had a potential for sunburn. I spent the whole bike ride at Eagleman letting them know so they can pull down for the sake of sun protectant!
