This is an interesting question, because you can’t necessarily donate them to Goodwill with last year’s blue jeans! Have you thought about keeping the bottoms and selling the tops? (I make this suggestion because I doubt anyone will buy the used bottoms.) Or, you could mix and match between outfits to create “new” ensembles. As for the one-piece attire, perhaps you could keep them and rotate your wardrobe so that clients don’t see you frequently in the same outfit.
