These are excellent medium support bras. I have them in 34C and use them for any physical activity that requires running, jumping, and/or sweating. They have some shape which avoids the tube-top effect, but could be better. Before I lost a large amount of weight and was larger-busted (DD), these bras were great at minimizing under my button-down uniform shirt. They are high-quality and long-lasting (5+ years and still going). My reason for buying these from Amazon: 50% cheaper than in my local store!
