We noticed this wee trend waaay back at RAFW, both on and off the runways. Red trousers were the strides of choice for the front-row fashion folks (thanks in part no doubt to Isabel Marant making cropped leather strides look somehow so freakin' cool), and ever since we've seen them pop up in editorials, look books and snapped on the street. Celebs are now taking to the trend too, with Katie Holmes rocking said Isabel Marant trousers yesterday for her appearance on The Late Show, and cutie-patootie Rachel Billson donning an Erdem blouse and pant combo today for the TCA Party for CBS in Beverly Hills. Feeling inspired by the scarlet stride look? Get amongst it with our top ten red-trouser picks!
