One of these days, I'd enjoy making myself an example of a Pre-Raphaelite Aesthetic-Style gown. Until then, I can admire the gowns made by Veda Crewe Joseph on this page.
The below dress looks like it could have come straight out of Jane Morris' closet!
And while I'm admiring aesthetic gowns, check out this actual vintage gown from 1910 or so, that has clearly been influenced by the aesthetic movement, and artists like Mucha. Gorgeous!
And finally, another vintage Aesthetic Pre-Raphaelite gown I found somewhere online, and lost the link! Be sure to click the picture to see it large and lovely.
For more information on artistic/aesthetic dress, check out a blog I did a bit ago, here.
