This isn't about the sex side of it momre about the image to go with it...

I'm just planning on suprising my boyfriend this weekend and I want to know if anyone has any tips.
I'm not thinking sex tips...
I'm thinking what to wear? do with my hair(it's very long and very brown)? what to buy?!
I'm looking for something sexy bordeline slutty but I don't want to look cheap.
Also I'm looking to spend about £100 (give or take) but time is of the essence, e.g. I couldn't mail order anything from the US or w.e
Thanks
