Hi girls- I wear the Seamless Sport bras and I love them, so much that I want to try the ones with smaller straps to wear under my regular clothing. Do any of you know the difference between the Seamless Wool Support Bra, and the Seamless Wool Bralette? I am guessing that the support bra has more support (duh) but I was wondering if the fabric in the front is thicker. I have a real "headlight" problem, those babies just don't lie down.
