  • sweatpants logic in corporate pinstripes 
  • 69% Polyester, 29% Rayon, 2% Spandex
  • Relaxed barrel leg with a high rise and full length

Named after Kiki, the other half of the powerhouse duo that keeps our office from burning down, these slacks are a complete optical illusion. They deliver sharp, boardroom-ready pinstripe energy on the outside, but operate entirely on sweatpants logic on the inside thanks to the elastic drawstring waist. You can rock the barrel leg fully wide or taper the cuffs with the adjustable buttons depending on the day's vibe. Made from a highly breathable rayon blend, they let you look like a functional adult while keeping your comfort levels maxed out. Pair them with the Sabrina Vest for the full anti-corporate suit.

Fit Tip: MEN'S FIT / RUNS LARGE. Designed with a roomy, full-length men's cut. The elastic waist provides a forgiving fit—we recommend sizing down for a closer fit, or ordering your usual size if you are between sizes or prefer extra room in the hips. Olivia is 5'8" and wears a size XS.
