Vans for £33. good deal for vans, which allways look good. you may not want white but hey, have a look around ASOS.

Different jeans may be a good idea with this jumper. but it is still a nice jumper that looks warm, but not amazing quality as it is only £17.

£17.50
So £75.50 for 4 things. and that is approx. £18 an item, and that is pretty good, and cheap for my standard. so maybe expensive for you, but its still cheap really. looking good is expensive!
