A lot of times the items you’ll get in a consignment shop will be better quality than a thrift store, but you can usually expect to pay a bit more too. Consignment clothing stores can be a great option for kid costumes. We usually find that there is a lot more kid costumes on Craigslist than those for adults, but it doesn’t hurt to check throughout the year. Craigslist may not be the best place to find a handmade costume, but it’s not uncommon to find costume listings.
