Sieve styles are the best!

Since I discovered Negative and their line of bras and panties, I am officially obsessed! This brief is both comfortable and sexy. The navy color is awesome!

Heavenly

I didn't know I could love a panty more. I am about to trash all of my others and replace with full set of sieve. They are so comfortable and flattering. I love the higher leg. The band is so soft. LOVE
