Firstly, every girl loves wine, therefore I've found these really cool, stylish wine inspired valentines gifts for every reasonable prices at Home Wet Bar. My favourite is the cage wine glass for corks - this would look great as a ornament in her home. My mum actually saves her wine corks in a large glass vase and looks great went filled. I've never seen anything like the candle holder for the wine bottle - this is a brilliant idea and perfect for a romantic meal on valentines day if you choose to cook a dinner at home. You can never go wrong with a stylish wine glass either.
Secondly, perfume, make-up and skincare are another great gifts for her. I particular chosen the top selection from Debenhams gift guide http://www.debenhams.com/beauty/gift-sets. With the above gifts - skin care products such as Bare Minerals, nails inc and make-up from Benefit, and YSL perfume are all huge brands within a girls mind and believe me your lady will adore you if you give her any of the above products as she can use them for everyday.
For further gift ideas, I found this gift for her guide on Instyle which may also be helpful for looking for that ideal gift for her.
