Just off the beaten path of bustling Main Street in Edgartown, up Summer Street a little ways, sits Once in a Blue Moon. The storefront looks like the first floor of a converted house, but that's where the similarities end. Inside, the shop is exquisitely decorated with an accent on modern form and function with beauty. Ellen greets customers with a smile and an intuition all her own. Her style radiates from this little shop where she sells a huge array of jewelry and women's clothing. "A lot of this is from Europe" with German and French names like Oska, Rundholtz, Elemente Clemente, Lauren Vidal and Spirithouse, among many others that decorate the walls and racks at the little gem.
