Reviews

everyday go to

"This is my everyday go to. Took a moment to figure out the sizing and I had to size up a little for the band not to be too tight and restrictive. It is also a bit of a high/wide cut around the armpits for me (which doesn't always work with camisoles) but it is such a comfortable bra! I have it in two colors."

— Nikita P. (5/5)

Ok bra

"I like that this bra is organic cotton and soft. It does have some issues though. I feel like it doesn’t hold my cleavage that great because when I bend over, everything spills out. Also, my nipples show through in most shirts. The other thing I don’t like is that the seam is pretty visible."

— Taylor T. (3/5)

Cute but not for me

"I returned this bralette because the 2 layers of fabric did not adequately obscure my nipples. Otherwise, it's a cute and nicely made bralette. Just not what I'm looking for in a daily bra."

— Yuki M. (3/5)

Everyday bra

"I love this comfy bra! Great for every day."

— Mereena (5/5)

I was so excited about

"I was so excited about this but unfortunately didn’t work for me even though it’s very well made bralette it’s missing different sizes of cups. I have ordered xs which is great around the chest size but unfortunately cup size was too small for me and I am not particularly bigger chested. Otherwise lovey bralette just didn’t work for me"

— Kristína I. (4/5)

Love it, but could be

"Love it, but could be more full coverage. I'm a D, so. Very cozy, and nice neckline. It's comfy and non agitating, perfect under a cardigan or tee, layered. I'm trying to transition to all cotton, hemp and linen and this is a good and affordable step."

— Olivia T. (3/5)

Very supportive for at triangle

"Very supportive for at triangle bra, super soft as well"

— Julie W. (5/5)

Comfortable

"Comfortable, band size is larger than the flex bralettes. I prefer the flex bralettes but this is nice and likely more bloat friendly. Both are super comfortable though. Only wish was that it had padding."

— Lauren M. (5/5)
