Crumple the ExOfficio Women's Savvy Skirt, shove it into the bottom of your bag, and begin your travels. When you pull the Savvy out for dinner later, it's wrinkle-free. This crinkly, lightweight ExOfficio skirt has a touch of stretch for a comfortable fit and a side zipper for easy on and off.
I tried the Small in this skirt, based on the Ex Officio size chart, but the skirt was huge on me, so I returned it. Seemed like a nice enough skirt -- a bit sheer, so I'd wear a slip with it -- but I wasn't motivated to try the XS size. (Wasn't sure if it would fit; wasn't sure how much I liked the crinkly fabric, or if I liked it $50 worth.) Might be great for someone else; just order down a size or two.
