Aries women are action people. Typically they enjoy fun gifts rather than practical ones. Things they can play with or use in an activity are always a good choice.
A surprise day-trip or mini-adventure will often impress an Aries woman more than many physical gifts will. Perhaps rock climbing lessons, or a trip to a theme park with big rollercoasters etc. If you want to really fire her up and don't mind killing yourself, then some kind of extreme sport such as bungee jumping or parachuting together would really impress her, especially if she's never done it before. Just don't be surprised if she wants to go again while you're still kissing the ground...
If you want to buy her lingerie then go for the risky over the classy. Most Aries women will wear clothes that would make others blush.
