Amy Larocca caught up with Beth Buccini and Sarah Easley, the owners of downtown fashion palace Kirna Zabête, outside the Sari Gueron show yesterday (Beth is on the left). They broke down their outfits — Stella McCartney, Chloe, Jean Paul Gaultier, etc. — and explained why their tradition of exchanging one item of clothing is a little different this year. (Note: A short ad appears before the video.)
