I had high hopes for this bra having read others reviews. I'm a 34D/DD in normal bras and do jog regularly. I usually wear an underwire sports bra with a tight compression bra on top to be able to jog without bounce. I ordered the 34D and 36D as I'd read it is hard to get on. It took me several minutes, seriously, to get the zip done up! It was easier to do up the larger size but then it was not as tight and far too much jiggle when jogging.  There is no underwire and no adjustable shoulder or back straps, so it felt just like any other compression bra once on (uni-boob and all). I have returned it and bought the Champion Double Dry underwire which was much more comfortable, versatile, and better value for money.
