"Elegant lines, and the ruching at the waist really flatters a real body. I ordered it straightaway and it didn't disappoint — it fits exactly as it looks."

"The packaging looked refined. When I opened it, the floral print was very close to the photo, delicate and romantic, though in person the colours were a touch less vivid."

"Gorgeous dress, but do be aware the sizing comes up small — go one size up. Once you've got the right one, the structured waist and flowing skirt are worth every penny."
