ALL IN THE DETAILS

We tried and tested every mesh we could get our hands on until we found the one: it had to be soft on skin, lightweight yet supportive, and a premium quality that would hold up hundreds of wears and washes later.

Briefs

Whether you do low rise or high rise, our signature power micromesh keeps it all held and smooth.

Thongs

The perfect everyday thongs are comfortable, breathable, and semi-sheer.

“I am obsessed. I have not taken this bra off since I put it on. It is so comfortable and is so sexy and I have told everyone to buy it.”
