1855 Robe à Transformation The Metropolitan Museum of Art
The above outfit is the kind of thing Dimity might wear. It goes from a walking dress to a ballgown for evening. On can imagine how lovely the ruffles would flutter in the breeze strolling though Hyde Park, or on the dance floor as she whirls around with a partner.
1859-1860 Robe à Transformation The Metropolitan Museum of Art
Because this one is a little more plain, and the neckline more reserved, I would say this is intended for a younger lady, or a pious older spinster. The height of the neckline also suggests a dinner dress, rather than a ballgown, for the evening option, but it's hard to say with confidence either way. This is something Agatha might wear.
1875 Robe à Transformation The Metropolitan Museum of Art
The above is something a little later in time that perhaps Felicity Loontwill might covet. This one is a ball gown and a day dress that might make for an admirable picnic outfit.
The concept of a Robe à Transformation ties, in my head, to the idea of a dress wit a matched over jacket. Here is something of that ilk for Primrose to wear on a long cold dirigible ride.
1894 Carriage Ensemble Charles Fredrick Worth, The Metropolitan Museum of Art
I love this next one from the Gibson Age because it really looks like a completely different outfit as a elegant dress and as a walking ensemble.
1905 Robe à Transformation The Minnesota Historical Society
This idea never did die. Think about today and buying a modern suit. Often a lady can get a skirt or trouser option (sometimes multiple different kinds of skirt and trousers) and then a jacket and sometimes also a vest.
1954 Ensemble Christian Dior The Chicago History Museum
The above ensemble is transformed simply by the addition of a matched shrug.

A funny thing about transformation dresses, both now and then, is that the evening portion tends to be less well covered, which is fine if you are dancing up a storm or milling about the convention party rooms but can get cold. On the flip side the more well covered option is daytime appropriate. This actually works in my favor most of the time as I get cold easy and most event spaces have the AC cranked up.
I think I have a particular love for this kind of dress because its so versatile and with one purchase there are countless variations. This is also great for traveling light.
Retro Rack is also on facebook where I post additional images and fashion thoughts.
