Hi, please can you advise me? DSis has asked for clothes for her DCs for Christmas, I have chosen for the younger ones but for 17 year old DNiece I want to get a voucher so she can choose for herself. Which shop would be good? I really don't know where young people shop now! She is tall, very slim, cool in a slightly geeky way. I am planning on about £20 or £25 so not anywhere massively expensive. Thank you!
