by Claudine Zap Jeggings, the jean legging, first surfaced as a curiosity over a year ago. But beware: The leggings designed to look like skinny jeans are now a full-on trend. Topshop , the British low-cost fashion retailer, deserves credit for coining the term for the jeans and spandex hybrid that will soon be on legs everywhere. As New York Magazine put it, "For that suck-it-in, painted-on look without the loss of circulation in your lower half." OK, well, sure.
