Pillion belt and kids bike gear wanted

[Feasty]

So my daughter is desperate to get riding on the back of my bike, she's nearly 11 and finally my other half has succumbed to letting her!
I don't have a huge stash of cash - and knowing kids she'll ride twice and get bored...

I've found her a brill protected jacket for a steal (£15), but still looking for trousers and other bits and bobs.
So just asking if anyone has one of those pillion belts lying around they don't use anymore?
I'm also after protective trousers for her but not coming up with much in my area, or that anyone's willing to pop in the post. She's tall for her age, so sizing would need to be for a 12-13yr old.

Helmet is gonna be the only new purchase, just don't want to risk 2nd hand or going cheap for that.
