Inspiration: Black Historical Gowns

On Pinterest I've seen a lot of black gowns recently, and with winter ahead of us I think these historical garments would look fabulous for the party season - especially those 1920s dresses!
Here are some examples that I found particularly beautiful.

Here are three examples of a 1920s robe de style, which someday I am hoping to make in black taffeta or silk.

Edwardian women in black.

1930s gown with an inset of cream lace.

I haven't seen a date for this dress, but I think it is from the 1950s? Isn't it gorgeous!

Another two Edwardian ladies wearing black, curvaceous gowns.

Princess Dagmar of Denmark in 1866. I love the sleeves and hair!

And finally, another example from the late Victorian and early Edwardian period. The stripes are divine, and that hat is drool-worthy; I think it has white bird or angel wings on it!
