I'm writing a Regency romance, and getting out of the mindset of the 21st century and into the 19th is a challenge. Images help.
Try it. Go to the Images search on Google, or the search engine of your choice, and type in your query. This image came up when I searched on "Regency lady". Click this link to see it in its original context.
You can do a lot with image searches: find house plans, scout locations, etc. Just don't spend too much time on it when you could be writing. ;-)
