I have had this bra for 7 months now and wear it most days to work to make pumping faster. For reference, I'm usually a 32D and I ordered a medium, which fits well although as I keep losing weight (5'7", 140 lbs) and the elastic starts to wear out, I wish it had one smaller band size.

A few things I like:
1) It's not hideous. That counts for something when nursing.
2) It works - I can put my flanges in and continue hands-free.
3) No underwire, which was especially nice in the early days.
4) Seems to grow with meI don't get gaping or spillage.

A few down-sides:
1) It doesn't hold the flanges in as tightly (especially over time) as my zip-up strapless pumping bra. (I have the Simple Wishes Handsfree Pumping Bra and it's GREAT.)
2) It doesn't do much for my boobs. It's very thin (no padding, which is to be expected). I'm not sure if it's my nursing boobs or the bra but they're fine, just definitely not as shapely as when I'm wearing a more structured bra with padding.
3) The bottom band does curl some. It doesn't bother me but it would be nice if it laid flat.

READ CAREFULLY: It does not have easy access for nursing. If you go back and forth (as I do periodically), I just pull the material up or down but make sure you read the description fully to know if this is what you want.

In short, I would probably buy this again but might shop around for something with a bit more structure next time, especially considering I use it many times, most days. Probably not ideal for larger breasted women.
