Fun Shack Anglo Saxon Costume For Kids, Celtic Tunic Outfit For Boys, Historical Dress-Up Costume For Parties

My son is 10, what size would I need to order?

You only have xl if for 9 years old would this be to big? As you say I need a large? Thanks

What size are these need one for 9 years old only says medium or large?

This is perhaps a stupid question but is the £99.99 a mistake? I like the costume but not sure I want to spend £100 on it?
