1-800-KILT-ANON?

Really, I think it's a function of closet space. Calculate the total dimension of all your closets. Divide by the volume of one kilt to get your maximum kilt capacity. Subtract by (the number of jackets you have to own + (5 * shirts on hangers)). Finally, call the contractor to provide you with an estimate for converting your spare bedroom into a storage room.
