In Love!

This bra is everything! I don’t ever write reviews but felt I had to - I bought the bra because I thought it was pretty, and came back and bought it in every color because it is so pretty and SEXY, and flattering, and COMFORTABLE, and it gives you a gorgeous shape. Best insta-targeted purchase ever! Thank you for making this mama feel and look so good. ❤️

The BEST most comfortable and sexy fit

I spent about $200 on bras at nordstroms trying to find a brand that works.... a bunch of one offs of these new bras and literally every si gle one went back. Then I got an add for negative (great job marketing team) and thought what the heck... return if they stink. But they ended up being so beautiful, comfortable and sexy I feel like a hotty in these bras and panties. I immediately ordered two more in different colors. Highly recommend!!! I’m 34D and the no wire works just fine for me.
