I was excited to order this bra after reading the reviews. It is great quality and has fantastic support, but it really, really flattens me, almost to no cup size at all, and I wear a D. It seems to run small. I had to reorder in a larger size than usual, both cup size and around. One of the straps is driving me crazy with itching but I cannot figure out what it could be since the straps seem perfectly smooth. For running it would be ideal since it holds a woman in so much.
