The first thing that came to mind when we really gave these sack shorts a good look was that it gives women the same silhouette that the thinnest of runway models has when they are literally bow legged from thinness. Is this why these shorts are the next hot thing on the runway? We certainly hope not. So far, and that said, we are much bigger fans of this silhouette when applied to trousers but maybe the whole thing will grow on us. Or maybe it will just get too hot not to wear them. At left, a pair from the Yves Saint Laurent Spring 09 show (Style.com's Sarah Mower said of the shorts, "...the concept of a garment that happens to be joined between the knees--worn with button-up shirts or tailored jackets--had gained a degree of visual inevitability that might be a staging post on the way to normality.") and, if you should want them cheaper and faster but still with a name you can drop to the street style photographer, check out Rei Kawakubo's pair for mass retailer, H&M.
