Use your pretty suitcases to store out-of-season items, thus freeing up closet space.
For the vintage suitcases I have, another side table idea: "For a dose of quirky charm, search flea markets for 3 suitcases in graduated sizes. Measure & cut a base from plywood to accommodate your largest case. Screw wooden furniture legs onto the base, paint, dry, & stack the suitcases on top. Use the suitcases to store off-season clothing & accessories."
