With regards to perfume...

I know fook all about womens perfume etc and the dosy blonde bint in the shop today was doing my head in so decided to ask here for some advice instead

Want to buy my girly some perfume for christmas, considering ive already got her 2 expensiveish pieces of jewellery I dont want to spend a fortune maybe £30-£35 ish, ideally. Whats good whats not etc...?

TIA
