Over-the-knee boots have come a long way from their Pretty Woman days. Eliminate the stigma completely with new thigh-high stacked-heel styles crafted from luxe suede and buttery leathers in wearable colors, like fawn, taupe, and gray, which feel more chic than scandalous. Slip them over skinnies for an easy running-errands weekend look or show them off with a high-slit skirt for an alluring effect.
