While the mere mention of the word jeggings brings about snickers and eye-rolling (who comes up with these silly fashion-industry names?), its rising popularity is undeniable. Hate the name, love the product. Jeggings are essentially part jeans, part leggings. With stitching and details to look like denim jeans, jeggings have the comfort and fit of sturdy leggings. I picked up a pair while I was in Korea last year, and have been living in them ever since.
