I bought this in my normal size 38D but it is too big.  I will keep it anyway because I don't want to hassle with an online return/exchange when I am not sure what my correct size should be in this bra. I have to wear this on the last set of hooks and put the straps up as high as they will go, then it is okay for strength training and low impact cardio, but the fit is still too loose to support high impact activities. The other thing I don't like is that the material is very slippery, so it is hard to fasten the hooks.  On a positive note, the colors are beautiful.  I got the mojito, which is a nice bright green.  A lot of sites only offer basic black or white, so you may need to shop around to find the pretty colors.
