Promising review: "I'm a 34 DD, and I ordered a size medium. THEY FIT SOOOOO WELL!!! My breasts are reined in without feeling like they are smashed into my lungs. I bought them for the gym and have used them for yoga, Zumba, cycling, jogging. Amazing. On me, they live up to the high-impact claim. Now I wear them every day. They give great support, encourage better posture, don't require constant adjusting, and are incredibly comfortable. They are my new everyday bra! AND I got five of them for $30!!!!! You can't beat it." —Strawberry
