Sometimes that dressy leather bag—no matter how sleek—is just too formal, too bulky, too much. Hence the appeal of these cheeky, mod vinyl totes in supersaturated colors by Loop (around $15). The full-size versions are about twelve inches high; the matching wristlets, just right for your wallet, keys, and watch when you’re at the gym, are half the size but no less sassy (around $9). Both come in four motifs—try a pair of stilettos kicking over a martini glass—and four colors.
