I need help! I am going skiing for the first time ever (somewhere around lake tahoe). I have found an obermyer ski jacket that fits and I like.. however I am having issues finding a pair of ski pants. I am from Oklahoma and we do not have many places that sell ski stuff for me to try on. I have tried on the North Face, obermyer, roxy, and Burton ski pants. Every single one I feel like I have the same issue. The size XS fits good(but maybe little too tight if I want to have a couple of layers on under) and the size Smalls fit way too big in the waist area. (and I have tried on ones where there is Velcro on the side. That helps a little with making the size smalls fit better but I am still nervous I might be pulling them up alot). Please help on any recommendations(brands, which size I should go with, even what I really should or should not wear under the ski pants!) Thank you so much in advance!!
