Back in fall, we were ecstatic to hear that Kate Spade was prepping to launch a lower-priced casual line. Well, get your credit cards out, ladies, because Kate Spade Saturday—the designer’s more youthful (and more moderately priced) fashion and home line—has finally debuted with a cheerful e-tail site. The line includes summer dresses, oversize jewelry, canvas bags, and home trinkets, all in Kate Spade’s signature bright hues and preppy prints. Did we mention prices start as low as $4? Go now. Go right now.
