If you ski or are thinking about starting to ski, this blog is for you. I have personal experience on this topic, having skied since I was 13. Fortunately, times have changed and you can now find ski pants that are practical and stylish. There are several styles to choose from:
Bib-Style protects you from the elements but has the disadvantage of being a little harder to put on and take off-http://www.justgear.com/winter/products/womens/RAWIK___7316A.asp

If you want your ski pants to look more like pants or jeans, take a look at the Spyder brand-http://www.usoutdoorstore.com/outlet/spyder-circuit-ski-pants-womens.html

If you are a plus size woman, try the Junonia website and their Plus Size Alpine Black Ski Pant. I don't have any experience with this brand but the description sounds really good. http://www.junonia.com/products/alpine-ski-pant/452100-3-545-596.htm
 
The most important thing is to go out there and enjoy skiing!
