Kendall Jenner and Gigi Hadid will do just about anything for fashion, including bleaching their brows and wearing corsets so tight it's a miracle they can still breathe on their own. Paris Fashion Week has been no different, though slightly less dangerous, with the two of them swapping hair colors for the Balmain show today.

Gigi walked the runway in thigh-high boots and long brown hair that looked so good I wondered why she hasn't gone darker before IRL.

While both Kendall and Gigi most likely wore wigs for the occasion, it's pretty clear that they can rock just about whatever's thrown at them. Seriously, Kendall, have you thought about going blonde before?
