Form and comfort!

I am in love with these bras! Smooth under clothes and super comfortable. The straps don't dig in either. I prefer underwire because I want some shape for my larger chest. I got the triangle sieve bras too and didn't like that they sort of flattened my boobs. So I'm exchanging those to get more of these!

Bonus: my husband says these are the sexiest bras he's ever seen.
