If you want to show your girl that you're clued in on the latest trends, then I have two words for you: leather jacket.
The leather jacket trend has been going strong for a while, particularly in tight, cropped styles. The best thing is that it's a classic item that is so right-now, yet also an investment to hang on to.
For a classic style, check out the biker jacket by D&G (above left) or for a cropped there's always the Kate Moss for Topshop take.
