I have had a different style Glamorise bra in the past and valued it's crazy support.  What I wanted to try was a zip front and a solid back in my current much smaller size.  I bought a Victoria's Secret zip front and found it almost impossible to put on--(probably my long claw like nails didn't help, but mostly I had a hard time holding the two sides together in a way that enabled me to get the zipper in and up)  I read a bunch of reviews on this one and sized up as what seemed to be needed.  I wear a very steady 36D in Body by Victoria lightly lined bras.  I wear a 36D in Werners bras.  I am a little bit bigger cup in Victoria's Body unlined--I need a 36DD as I seem to spill out of the cup on one side in my regular 36D size.  Based on the majority of reviews I ordered a size up--38D.  It was HUGE.  I figured I'd just use it to garden in--I hate returning things.  Next I ordered my regular size 36D.  The cups were still big, but the band fit perfect and was easy to get on. Ok, so now I have two gardening bras.  (I've recently lost 50#'s so my struggle to replace an entire wardrobe has been challenging when just a simple size down doesn't fit like it used to--I'm NOT really complaining as I love my new shape...)  So now I'm on order 3---I figured this is it.  My regular size 36 fit perfect and the D cups were big, so my last order was to try a 36C.  I don't own ANY C cup bras and this one supposedly runs big--go figure.  It fits better but kinda weird.  it's not nearly as supportive--there seems to be some wiggle room.  It doesn't have much in the way of a liner---nipping will be a definite--not that I mind that so much because the material is somewhat thick, so it will be subtle.  It's just that the cups made my boobs a weird small centered almost cone-shape that didn't feel supportive for high impact activities.  Ok, Well now I have 3 solid gardening bras to wear under loose tank tops and my search continues for that elusive high impact JUST RIGHT bra.  OR maybe I'll just keep struggling with that Victoria's Secret Bra because once on, it was good.  I figured I'd leave a review so as to save any other normal 36D wearing bra folks some time and money--you do not have to size down if you are roughly my size.  I'm just under 5'9" and weight 155 pounds, wear a solid size 8/Medium in most clothes with a bit of dipping into some size 6's & lastly I'm a solid 36D bra.  Good luck and good bra hunting!
