In Honor of Ralph Lauren's 75th Birthday, See 40 Celebrities Wearing His Designs
It's a big day for Ralph Lauren! The designer turns 75. From his designing iconic movie outfits (he worked on Diane Keaton's wardrobe for Annie Hall) to his red carpet delights, Lauren has masterfully kept fashion lovers in awe. A more recent example is the launch of his Polo Tech Shirt, a smartshirt designed to monitor the wearer's heart rate, breathing and stress levels, transmitting the data in real time to a computer or phone app. Color us impressed.
