Angie's post on leggings prompted this question. How do you define jeggings? I have pants that are denim and I like to wear under casual tunics in cooler weather -- for some reason they just look better to me than leggings. They do zip up (not pull on) but are tight fitting on the legs -- like leggings. What is the difference between skinny jeans and jeggings? Also, are jeggings out of fashion? I was not clear on that from the leggings post.
