Like killer shoes or the right bag, a haute mani gives validation to the rest of an ensemble.

Pick the right one - like Chanel's Jade, which the company created to enhance the threads in its fall tweed, pictured below - and suddenly any outfit has the potential to become that coveted thing known as "A Look." No wonder designers and their hired nail gurus labor over which season's shades are right for the runway.

Check out the shades that made the cut this fall, below, and see another hot fall beauty trend (hint, it's totally tubular) here.
