Good that you found some ski pants that fit.
I have discovered that when looking for specific items and specific sizes, shopping on-line is the way to go. I wear a 13 shoe. The shoe selection is much better on-line than it is in stores. Being built something like my ape ancestors, I have rather long arms. Dress shirts are always easier for me to find on-line than in stores. I wear a 17 1/2 with a 36" sleeve length just in case you'd like to send me a shirt as a gift. 
I hear you there... I shop 95% online lol, talking about 14-15 shoe sizes, 38-39 dress shirts sleeves (thanks to manswearhouse) and lots of good sizes at bananarep so yeah online is the only way to go which is good since most have free returns/refunds
