pemberleyserena's post asking what made you (all) fall in love with Regency reminded me I should probably photograph my favorite early dress in my odd little collection. It's, I guess, really late Regency, just barely pre-Victorian.
The dress is done in the 1820's style but I think it's more likely late 1810's originally. The dress was clearly made for a young girl given the length (I'd say it would fit your average 8 or 9 year old today). It has a growth pleat and the skirt is tucked up into the dress enough you could easily let it out another 3" without letting out the pleat.
I love this dress because it's so simple but pretty. The fabric makes the dress. It's hard to see via computer but it's a very nice purple ink color design on the white (Indian?) cotton. The dress just looks like summer.
