- MSMonica S.Verified BuyerReviewingTriangle Bra | Pink SandI recommend this productAge Range 35-44Rated 5 out of 5 starsNov 4, 2024So comfortable!
I love the fit, material and style of this bra. The band and cup sizes are perfect and the material is so soft and comfortable. The cut out is really fun and honestly makes me smile every time I put it on! The band quality and the front adjustable straps are the two major differentiators. It’s the most comfortable bra I have and can’t wait to order more!
- LBLibby B.ReviewingTriangle Bra | MahoganyI recommend this productAge Range 35-44Size Purchased SRated 5 out of 5 starsOct 9, 2024Comfortable, smooth and supportive!
The bra is exceptionally comfortable, with breathable, smooth materials that make it ideal for all-day wear. I normally wear a 32D and ordered the Small.
Despite being wire-free, this triangle bra provides a really nice amount of support. The wide band under the bust keeps everything securely in place and the ups have plenty of coverage for my shape. It’s perfect for those who prefer a more natural look and feel while still wanting a bit of lift.
IiterationFeb 25, 2025Libby, you just made our day! 😊
We’re so happy to hear that our Triangle Bra is hits all the marks for comfort, support, and that natural look you love! Knowing that the breathable, smooth fabric keeps you comfy all day long—and the wide band gives you that perfect, secure fit—it means the world to us.
Thank you for sharing your experience and for trusting us with your comfort. We love having you in our community! 💜

I have never (NEVER!) bought myself a nice bra. BEEN SERIOUSLY MISSING OUT! So well made, such great attention to detail, and fits amazing. Super comfy, practical but I still feel 'pretty'!

I am so happy with my purchase of this bra — I bought it in two colours! The fabric is so smooth and luxurious, and it's a super comfortable bra — and supportive too. I will be buying more of these for sure. They're my new go-to!
