I need to buy a Christmas present for one of my daughters oldest friends, a family friend. This girl is 13 and one of the most popular girls in school, very much aware of trends and brands. She is lovely, funky and cool. Her dress style is sort of street dance - not particularly feminine or romantic, I would say. My dd suggested getting her perfume but I have no idea what I'm doing. I think I could get her something appropriate for around £15-£20 - any ideas?
