The plaid shirt used to be associated with Grandpa on casual Friday, but now it’s more often seen at your local dive bar on the back of your friendly neighborhood hipster. The look works for just about everyone, though, not to mention earns points for comfort and ease of picking out of the hamper on a late morning. But if you’ve been hesitant to take the dive into the plaid button-down trend, here’s a good way to start with one of the dozens on sale at JackThreads.com, a community-based menswear site that offers up daily deals on streetwear and skatewear. The site is members-only, but it’s free to sign up and the sales are worth it. Get the Aknowledge shirt on the left for $38.25 and the neutral, black-and-white Alphanumeric shirt on the right for just $21.99, both more than half off the original price. It’s a steal for any button-down, and dirt cheap for the brands; sale ends Thursday!
