Speaking of openings, this one we can definitely confirm, as can you if you’re in Chicago tonight and want to go to the party of the month. Threadless, everyone’s favorite purveyors of quality shirts and miscellany, have finally opened up their first retail shop here in Chicago and to celebrate, they’re hosting a big free concert, featuring a batch of popular local bands. If you’re interested in going, you just need to swing by the new shop (which we peeked into every once in a while as it was being built and it looks fantastic) to get a ticket. It’s at 3011 N. Broadway. Party starts at 6pm at the Metro.
