This is a pattern for a sophisticated dress that is bound to get you noticed! But please take note, this pattern is not really for beginners, but for more experienced sewistas. The Fifth Avenue Dress is an asymmetrical dress with a pleated collar that wraps around a modified sweetheart neckline. A skirt drape on one side offers design balance and visual interest. The pattern calls for crisp fabrics like taffeta, silk dupioni or satin.
