Sam Shipley and Jeff Halmos make great clothes, but their interests span far beyond fashion—and they’re not shy about reminding folks of this fact. The latest evidence? Their second annual March Mayhem Challenge, which is essentially a private NCAA tournament bracket on ESPN.com that nets the winner a $1,000 shopping spree on the duo’s site. If you haven’t filled out a bracket, you might as well join these guys. Just email [email protected] with the subject line “underdogs” and they’ll get you access. And whether or not you actually sign up, check back soon for the next Shipley & Halmos sale on Gilt. And for more on Sam and Jeff and their endearingly off-beat approach to their brand, check out my Q&A with the duo from a couple years back.
