Bra review

I like that’s it unlined and featherlight, like wearing nothing. It’s a great t-shirt bra. Love it

My favorite bra

This is the best bra I’ve ever purchased. It fits my measurements exactly and is supportive and comfortable without the frustration of bulk and rigidity. I come home from a long and busy day and the last thing on my mind is taking off my bra, which is an amazing departure from my experiences with other brands. I can even sleep with this on! If you’re a busty person who’s still looking for great support and no padding, look no further!
