Daughters 18th birthday

My daughter is turning 18 in a couple of months and so far I have only got her a new iPhone 8 which I know she wants. What else would she like in a budget of £250. I'm planning to do a surprise birthday party and get some of friends over too. I am lost for presents because 18th birthday is quite special and id like her to have special presents too this time not just the normal phone, jewellery, bag, shoes and gift cards..Any ideas?
