This style is so comfortable you barely know it’s there. It doesn’t dig in or move around. I can wear these for both everyday use and during my long runs and workouts, so this style gets an immediate A+ from me.

Amazingly comfortable. Impossibly sexy. The color palette in Sieve works so well you can easily mix and match bras and thongs for daily use. Doesn’t always have to be a “set” to look positively perfect.
