New York Fashion Week has officially commenced! So, what’s it really like in the lives of InStyle editors during the week? Their schedules are jam-packed, with shows on the hour every hour.

We asked them—from the fashion director to the fashion assistant—to reveal their most prized items that help keep them going from morning to dusk. Click through to see their must-haves, from travel-size lint rollers to coffee customer-loyalty cards.
