Red hair is a lot of look in and of itself, so pulling off a pattern can be tricky. Stick with understated motifs that contain colors that work best on redheads (see slides one and two) while avoiding busy patterns with blue- or gray-based shades. See how much hotter Christina Hendricks looks in her low-cut patterned top with redhead-flattering shades versus the too-busy, wrong-hued floral dress? (Yeah, yeah, the cleavage probably helps a bit, but the pattern is doing its part too.)
