Shops come and go. Unsuccessful ones barely linger through their first year's lease before disappearing. However, some are embracing retail ethereality. As part of its 20th anniversary, I.T has set up a 'pop-up' store in Times Square's second floor atrium. Opened since Monday, the box-like structure is filled with T-shirts and items the store had its many hip designers and labels create as one-off merchandise. From exclusive collectibles by Maison Martin Margiela, Ann Demeulemeester, BAPE, to Chocolate and Izzue.com, there's enough cool knick-knacks there to have most teenagers salivating. The catch is, you couldn't buy any of it until today. Starting at noon, the exhibit becomes a shop as all the items inside are for sale until Sunday. The I.T XX Pop Up Store is open until 9pm on these three days. Go early because the kids will likely blow their allowance budget until next year snapping up the stuff. After the sale, the shop and all its products are gone too - until they start appearing in online auction sites.
