Gift for 9yo girl help!

[ShesThunderstorms]

Anyone have any suggestions for a birthday present for a 9 year old girl?
She absolutely loves Harry Potter so I've got her a little HP toiletry bag but would like to spend around £15-£20 more.
I don't know any other 9 year old girls so I don't really know what's the cool thing or what they're into at the min, and I don't see her all that often so a more generic gift might be good as I don't want to get it wrong.

DDs favourites this Xmas have been GCHQ Spy Puzzles Book, Lego, mini (M&S) perfume, hair bands etc (oh and converse high tops but they'll be out of budget unless there's some in the sales).

Dunelm have fab Harry Potter Oodies if you can find out what house she is in

These went down well with my dc (8 and 10), they have a few different ones.

You can buy Harry potter Lego...sorry can't recommend an exact set but if you google, I'm sure you will find something.

Dd(9) loves Harry Potter and has this

Official Harry Potter Jewellery Silver Charm Bracelet for Harry Potter Slider Charms (20cm) amzn.eu/d/eZlF0dh

Although I think in the smaller size 16cm maybe?
It's better quality than you'd think for the price and the slider charms are £5-6 each, there are some really lovely ones. She had the bracelet and some charms for her birthday and we included a couple more charms in her Christmas presents

My daughter loved the Harry Potter Cluedo £14.99

Dobble game, nail varnish (Rimmel or similar not 'kids'), riddle book, stitch items, stationery (notebooks/pens - normally cute animals).

The surprise winner for my DD (8 and a half) has been a tamagotchi. I didn't even though they were still going. My DD loves it but it drives us mad!

Favourite HP gifts for my DDs have been...
House T shirts (m&s)
Socks (primark)
Stationery (the works)
Board games
Hedwig cushion (dunelm)
Lego

Other favourite gift is Lego Dots and books.

Loom bands were a surprising hit here.
