I already had one of these and purposely searched for it when needing some new exercise bras.  I purchased in both white and light taupe (beige).  It fits as expected and I ordered my normal size.  It's sturdy enough for heavy movement (I'm not a runner but I do a lot of aerobic step classes) and it's still very comfortable.  The modifiable straps are also a plus because you can wear it under different style tops.
