      Love this Bra

      Submitting this review during COVID-19 quarantine - all my friends are bragging about not having to wear a bra since they are in quarantine- I am bragging that I get to wear this (what I like to call) “no-bra bra”. I like to go braless at home but also feel as a 34DD gal that I need some support! This bra is amazing- it is so comfortable I feel like I am not wearing a bra but the girls are fully hugged by this non-wire bra. I was skeptical when I made the purchase that this would even offer support- but it does! LOVE LOVE LOVE this bra!

      So comfy!

      I have never been a fan of underwire, but also felt like a lot of bralettes make me look frumpy by not providing quite enough support. This non-wire bra is perfect! It gives plenty of support without digging in or suffocating your chest.

      Love This brand!

      So sexy, comfortable, quality, and happy with the aesthetic. I took a chance and I am happy I did. I went and bought a VS bra and even the man said he thinks these are sexier.

      Big Fan!

      Finally found a bra that works for me - comfortable and supportive but sexy and somehow durable enough for everyday wear. Love the color and definitely plan on ordering more!
