NWT Hill House Ellie Nap Dress in Wisteria. Size Medium About the Print Inspired by classic wisteria vines in the South of France, we worked with artist Leïla Dubus to create the soft greens, blues, and purples of this watercolor print. Wisteria is a classic summer floral - romantic, feminine and ethereal. Meet the wear-everywhere Nap Dress®. It’s our signature garment; soft, comfortable, and pretty enough to wear all day and night. The Ellie is an A-line Nap Dress® with our proprietary, elasticated Nap Smocking, ruffled shoulders, tiered midi skirt, and pockets.
