    Great bra!

    I really am loving this bra so far, I have had it for about a week. I read the previous reviews that said "fits small" so I sized up, which I wish I did not do. I had to do an exchange for the smaller size (which I should have got in the first place based on the website size chart). The online exchange process is very easy! I love the extra material at the bottom of the bra as it hugs against my ribs. I do not spill out the top or sides of the bra. I am large chested and don't have to readjust the bra or the "girls", they stay in place. As this is a medium support bra, I have only worn it as my day to day / lounge bra not to work out in. My only concern is that overtime I am afraid the bra will stretch? I really hope this doesn't happen. I have left it out to dry flat after washing, so hoping as I am following the washing instructions, it does not shrink and does not stretch (or else it will be to big again).

    Finally found a bra that's supportive that I like!!

    I don't like bras and don't like how my bust looks under clothing -- other sports bras either don't provide enough modesty coverage or are unsupportive. This bra is so comfortable I can even sleep in it without feeling constricted or sufficated. Lots of support AND it's (slightly) reductive in appearance! Definitely will buy again every time there's a sale! Love the colors too!

    Love this bra. With cups in fits great but a little loose around chest. This makes it super comfortable.
