I wear a 36D and I found this bra true to size and very comfortable. What I did not like was the support was not great. When I got it I tried it on and did a few jumping jacks and I was bouncing all over, no better than the inexpensive bras you can buy at any discount department store. In addtion the material is quite thin and my nipples showed through, not somehting I would want happening at the gym. I returned it. I would not recommend this for anyone who is doing high impact sports.
