Present idea for 16yo girl

[DameEdnasNeighbourhoodWatch]

Hi I am turning to you lot - I need to find a gift for a 16 yo girl - feeling stumped and I don't know an awful lot about the girls individual interests/hobby's !! Any inspiration from you guys ? I was thinking lush gift set ? Nail polish gift set ? What's popular with youngsters these days ? Please help!

Sorry for all the duplicate posts - there's a glitch which is causing all this bother at the moment. We've now deleted all the duplicates as far as we can see. Let us know if we've missed any though.

My teen nieces (16 and 19) were made up with some Glossier makeup I got for them at Christmas. I got them this lip collection.

A lush gift set sounds fine. Good skin care products or gift card for cosmetics shop will also do. If she's somewhat crafty, then DIY kits could work out as well: a candle making kit or a jewelry one. If there is a chance she loves photography (or at least posts a lot of photos on her Instagram or Fb), then maybe a subscription to photo editors, something that resembles Photoshop but isn't that complicated (like Photoworks or the Pro or Ultimate version of Photodiva).
I also think she'll appreciate something for her place, like led lights or a neon sign (something of this kind)
