As I write this, I've just spent an hour sorting out my sons' dress up costumes into new storage. It would have been quicker but my preschooler tried on almost every one!
Previously all the costumes were in big storage bags which meant that if the kids wanted to find a particular costume then everything came out. Also it was hard to find all the pieces and role play accessories that went with each costume.
Something had to be done! I looked into various storage options which I'll cover on this page. The right solution for you will depend on the kind of kids costumes you have, how many you have (or expect to have!) and the shape and size of the space you have available.
