I am not small girl by any standards. Over 6 feet tall, on the 'thick' side and very large chested. I recently started running to lose a couple LBS and train for a half marathon. When I started running longer distances, the 'girls' started taking a toll on my neck and back, causing excruciating pain. I would have to wear 3 sports bras and the straps would cause a strain in my trapezius that KILLED ME!! I bought this bra because I saw it on a website that suggested bras for girls with bigger chests, and because it matches my running shoes and gym top perfectly in the light blue ;) I wear either a 38DD to 38DDD in regular bras, so I went with the 38DD so I could get a snugger fit. Although after a while the strap gets a bit tight under my boobs, overall it fits true to its size. When I put it on, I definitely felt like 'they' got a lot lighter. I ran 5 miles later that night and didn't get the back pain I usually get before and after my runs. I have run many more miles since then....still no pain. They still bounce a little, but I don't mind that because the neck pain is gone. Definitely recommend!!!! :)
