Almost perfect, but heads up band is short

It's a very comfortable bra. The material is stretchy and soft. The only problem is that the band runs a bit short at the back. My understance calculator size is 32D. But, due to past experiences, I find one band size up more comfortable. This time, however, even a one size up is short at the back. I thought maybe I am too used to wearing a looser bra. But, after a day of wearing this bra on its normal hooks, I got marks all around me. Now I am wearing this bra with extenders and its working well. (Posting it here so others know before buying)

Insanely comfortable!

I have a very active life style and don't want to wear a sports bra while at work, this is the one. She stays in place, feels so soft on the skin and flexible. Highly recommend

Nice bra but not for me

I really wanted this bra to work. The fabric is SO soft and stretchy and so comfortable. But I just can't fill it out on top (even though it's supposed to fit bottom-full/even). The fabric is loose and quite wrinkled. I've kept it to wear under sweaters in winter but I couldn't wear it under a t-shirt due to the wrinkles. (For reference, my favorites are Nora, Zoe, Simone, Iris, and 32DD - 34D fits me very well).
