Almost Love

I almost lose this sports bra. The positives: Super cute (especially the back) and comfortable. Negatives: Doesn't quite fit. The bust size is just about right, but the band is a little too loose. I wear it for low intensity workouts and around the house. Just have to make sure the twins don't pop out.

Very soft and comfy, just not as high impact as I wanted

I could wear this bra all day and feel completely fine, but it isn't as high impact as I'd hoped it would be.

Great bra!

I love this sports bra! It’s super comfy and supportive, not to mention cute! I do have to flip the cup inserts over every time I was it, but it’s not too difficult.

Overall a good bra, just not true to size. I have size 8 in a couple other bras and they fit great. This one was a bit big.
