I was at the zoo on a cold night around New Year's and noticed a woman wearing an ankle-length version of my skirt. She looked GREAT. You would think that a puffy skirt would look bulky, but actually she looked athletic and shapely.
Skhoop of Scandinavia has a strong appreciation for puffy for those in cold climates. They carry insulated skirts in all sizes and lengths, but they are fairly expensive.
What a great apres-ski item! Are you starting to crave one yet?
