This is one of the most gorgeous dresses that I have ever purchased anywhere! It is beautifully made and looks exactly as pictured and is of very high quality; it was packaged perfectly. I am a US size 6/8, US 34D, normally M, 5'7" tall. As a first time customer I ordered both the S/M and the M - while both fit (the S/M more tightly in the chest), I kept the M as it provided more coverage at the bust and did not strain the invisible zipper (always a risk). The return shipping from the US was quite expensive ($40) but I'm glad that I could try both sizes - wish there was a shop to visit. Also, customer service has been excellent and has answered all of my questions. I would highly recommend this dress and so happy that I found this designer - I will be ordering more dresses for sure!
