My stuff completely fills one full-width drawer and one half-width drawer of a 5' wide wardrobe, and there are still a large number of items scattered about elsewhere...e.g., all my gloves and glasses are in one of those over-the-door shoe holders (though oddly, my cycling shoes are not kept in that), and I've got a winter jacket and a cool weather wool jersey that are on hangers in the wardrobe.
Yeah, definitely too much kit! I wonder if I could trade some clothes for more bikes?
