Angel Chang, the high-tech fashion designer, has her wonderful heat-sensitive map T-shirts currently available for sale. The T covers Manhattan’s trendiest districts—Soho, Nolita, and Chelsea— so you’ll never get lost shopping or gallery hopping. Available for $80 via Angel Chang’s website. BTW, Angel is currently a contestant on Bravo’s The Fashion Show. I haven’t seen a single episode yet so I’m not sure how much of her interest in fashion + tech she will bring onto to the show — I’m curious to see how it all unfolds.
