Reviews

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 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)

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)

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)

The Core Triangle Bralette

"I am a tried and true return customer for the Core triangle Bralette. It is my staple. The fit is amazing. There is no digging uncomfortable straps. There is no pulling on it all day long. It just fits. Smooth. Comfortable. Always."

— Heather 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)

Wear with anything!

"This bra is so comfy and I really like the color. Perfect cozy lounge bra but also sits nicely under any top if I want to wear it out! It’s the perfect amount of lift and support from a wireless bra."

— Josephine S. (5/5)

Very happy

"I am between a Small and Medium size, so I ordered the Medium although I was worried the cups would be too big for me. The bras are actually a great fit though, and super comfortable! The fabric is lovely as well."

— Sarah K. (4/5)

Best Bra Ever!

"I have been looking for a bra that fits my larger 38 band size and smaller A cup size. That size combo, especially with back hooks, had been impossible for me to find. I also wanted organic fabric, especially for this first layer/all day wear--and I'm thrilled to have found the Core Triangle Bralette. The design and thickness of the fabric is perfect, with no awful underwire--it's very comfy and flattering. Plus shipping was incredibly fast and customer service was quick, friendly, and helpful! I'm 5'7" 175 lbs, bought the XL initially but exchanged for a L and it fits even better. You really can't go wrong with this bra--the price point is great too!"

— Tiffani G. (5/5)
