HAHA! So true... anyway: if she likes urban outfitters, try this website:

There is always THIS too if she's been your girl for a while - get a super cheap purse from Forever21 or Urban Outfitters somewhere and stick this little signature blue box in it with a nice silver bracelet w/ a snowflake charm. That's going to be a very expensive gift tho with the charm and the bracelet, but if you've been with your lady for a while, I'd say it's a good choice.
Dunno if you have a lot of money or not, but also Ugg Coquette slippers are amazing, you can wear them outside and after skiing, and damn, are they nice/comfy/warm. I used to bash UGGs constantly, then I tried some on, then my sister bought me these to wear after skiing and such, now I wear mine all the time in the winter and they're like pillows for my feet after skiing all day/doing archaeology/anything really. You could stick them in said purse. If purse was around $20, the slippers are around $80.
If you're kinda broke get a purse from Forever21 and then put ski stuff in it, like "The Way I See It", some wax for her skis, maybe a pair of Smartwool socks, maybe some lip stuff with high SPF, lots of nice things that she'll like that aren't too expensive that she can use. Useful things are just as nice as pretty shiny things that sparkle.
