Reviews

Nice fabric, tight underbamd

"Good quality fabric, lovely range of colours. I returned for a + size, even though I am not big busted and I find this option offers better coverage and support, allowing for a more dynamic and active range of movement, but I think the under bust band is far too tight, does it really fit anyone when done up at its smallest??"

— Tatiana C. (4/5)

Overall really nice, the fabric

"Overall really nice, the fabric is soft but holds everything together. I only wish it gave a little bit more support or thicker fabric, but still a good fit. The straps are wide and therefore really comfortable"

— Luisa M. (4/5)

The quality of the fabric

"The quality of the fabric is fantastic and makes this bralette so comfy! Provides good nip coverage without padding. The red color is really pretty and feels a bit fancy. I’m 5’9 130lbs and normally wear 34B, the small fits perfectly."

— Alaina B. (5/5)

Really comfortable. Gives a boost

"Really comfortable. Gives a boost somehow and so very flattering. Plus from a b corp? Will buy again 100%"

— Diana G. (5/5)

Soft and comfortable

"I love that the material is organic and this is very comfortable and makes my boobs look nice! This is going to be my go-to bra now for sure."

— Helen B. (5/5)

Very comfy bralette and flattering

"Very comfy bralette and flattering the breast. Also there is no metal or other annoying material that goes into the skin and hurts like some other brands. They don't feel like putting the boops in jail, which is great."

— Sarah S. (5/5)

most comfortable bra for sensitive skin plus size

"I have sensitive skin and this bra is so good at protecting it as the band is fully covered in cotton, not left in elastic. Other brands on the market do not carry larger sizes so this is the only option that fits. Worth the price for quality of materials and craftsmanship."

— Polly (5/5)

Super comfortable soft fabric!

"I bought a size S (usually wear S/2-4/30D/32C) and it fits great! Very soft fabric and no tags that make skin irritated. Great for lounging around the house or when I just want to wear something comfortable! Won’t be going back to the other brands I used to buy."

— Olivia (5/5)

The bra was incredibly comfortable,

"The bra was incredibly comfortable, but i don’t have the biggest chest and it flattened it out quite a bit extra. So while this design was not for me i still very much liked the quality and the softness of the product."

— Emma C. (5/5)

The best!

"This is my favorite bra to wear under low cut and strappy dresses. It's cut low enough that it won't peak out and the colors are super cute so it looks good if the straps show. True to size, fits perfectly. Soft and light but with just enough support."

— Camilla A. (5/5)
