as well. i dug out a few of my old student fancy dress and past hen party supplies for my kids recently. they are proving to be very popular (especially with my boys!).
the most popular items in our dressing up box are the superhero capes that i made for them last year. they were so easy to make as well. just take an old pillowcase and add two pieces of ribbon to make a tie. then cut out some felt into the shape of superhero badges and glue it on with strong glue.
i hope i have inspired you to go and start to gather supplies for your own dressing up
