Try a resale store. If you take store credit instead of cash, it will usually be enough to buy a new set of clothes that actually fit. Not a one-one ratio, but maybe 5-1. We regularly take in a load of clothes to the resale shop. Even better, we used to stop at one store, sell, and then hit up another right afterwards with anything the other shop did not want. Because we had an only child, we would get tons of clothes from both sets of grandparents, overwhelming our little one's closet. Letting them wear stuff one time so grandma could see(or just take a pic and post on FB so they think they are wearing the clothes), and then selling them was almost a necessity.
