The designer calls this practically unwrinklable, super stretchy mesh “onionskin.” That should give you an idea of how little weight this all-purpose topper will add to your suitcase. It can handle being tucked in a tote bag all day and still help you look dressy at dinner. It’s long enough to cover your backside, with a flared shape from the waist down and an open front, no closure. The charcoal gray, beige, and red pattern is based on the inside of a nautilus shell and its mathematically repeating spiral pattern.
