Met Police appeal gift 17yo girl

[HereBeFuckery]

Inspired by the post for the 8yo boy, I would love some advice on what to get a 17yo girl for the Met Police gift appeal?
Budget £20/30, nothing battery powered.
I've heard advice before saying nothing that could be sold/used by others 

Was wondering about:
Boots gift card?
Lightbox?
Sweets?
Nando's gift card?

Anyone have advice? I don't have any 17yo girls around to ask for help!
Thank you 

Gift voucher is a good idea.
Makeup palette/brushes/vanity case/those acrylic storage thingies/light up mirror
Power bank
Headphones
Nice purse or handbag (River Island or somewhere 'trendy' like that)
Gift set of nice toiletries/bath bombs/hair care products
Set of mini perfumes

I don't know about the Met appeal but the one I do each year specifically asks not to donate food items (they do a separate food appeal) The stuff is stored beforehand so I suppose there's the risk food items could get damaged, melt or whatever.

Just thinking out loud:

Make up brushes
Makeup palletes (Revolution at Superdrug are fab and not pricey)
Nice quality chocolates
Decent quality shower gel / hair care
Leather gloves

Nice scarf, gloves, hat. Handbag is a good suggestion or anything cosmetic or makeup related. Things that would be a treat.

These are fab ideas thank you. I was assuming steer clear of eg headphones/phone related items in case she doesn't have a phone/electronics but maybe that's a bit unlikely?

I'd prefer to buy a 'gift' rather than voucher but maybe some nice makeup/smellies/purse and a voucher.
