You know - I cannot imagine how anyone could think those incredibly ordinary dresses are in any way comparable to the Alemais dress.
As for wearing it to a wedding or christening - absolutely perfect for a gathering of clans at the vast family villa somewhere on the Mediterranean coast. Would fit in gorgeously with the environment.
At a tiny 15th century village church in Wiltshire? Just think how many conversations it would start. Which can only be a good thing. I can think of other Alemais dresses I might choose ahead of this one - but that’s just personal taste. It would absolutely add to the fun and joy of the occasions.
A midday ceremony at a city registry office in Birmingham? Why the hell not? It would be particularly epic with a similar silk headwrap towering above the congregation.
