Following the opening of Been Trill's flagship on New York City's Canal Street, the brand has now teamed up with Big Sean on an exclusive T-shirt available only at its brick-and-mortar location. The T-shirt with a black and white photo of Big Sean in a Been Trill hat will definitely sell out before the end of the week, so if you're looking to cop your own, don't slack and head to 271 Canal St. right now.
