J. Crew Mirabelle dress in silk chiffon. I love that this is 'Matisse blue'...taken right from the Blue Nudes series. This is a pretty color as well as a great silhouette for a more conservative spring/summer event. I like the fact that it has little cap sleeves and proper underpinnings can be worn. Pair it with the Tipsy Skipper 'For Sail' clutch and jeweled ballet flats = ethereal.
