First up one of my all time favourite designers - Vivienne Westwood...
This Dress from Liberty is beautiful - if I could afford it, I would buy it in every pattern & colour!
The bio on the site describing the dress makes me want it even more!:
This fifties style dress nips in to enhance the waist, with a full skirt perfect for twirling around a dance floor.
