The Ubiquitous Blue Coat of the Regency Era

Hello everyone!  In preparation for making the beau's regency items, I've done a lot of research regarding men's Regency fashions (with a lot of help from my friends Brian, Maggie, and many others).  In case you couldn't tell from the blue cravat and blue vest I made Sam for the 1860's, Sam barely wears anything but blue.  I had originally planned on making him a black tailcoat from some suiting-weight wool that I had in the stash, but through researching I found out that isn't quite the weight we're going for in the Regency.  I kept finding more and more blue tailcoats in the era, and I came to the conclusion that 1. hopefully this tailcoat would last a very long time and I wouldn't have to make a new one for a while and 2. if they had blue tailcoats, then why the hell not?  I searched and searched for the correct weight of blue wool, but to no avail.  I came pretty close on some of the places I looked at, but either they didn't have the right weight of fabric or they didn't have the right color.  I even went to Joann's, of all places, but that fabric struck out on both accounts.  The night before the Market Fair at Locust Grove, I was talking to Maggie and mentioned my search, and she ended up having the perfect wool for me!  I can't thank her enough, especially because there will be enough left to make a pretty little something for me!  Anyway, enough talk, here are some of the many fashion plates and extant images that show this classic look.

And finally, the tailcoat and waistcoat fabrics I'll be using to achieve this look.  Wish me luck!

Edited to add: thanks to Betsy Bashore for helping me out on terminology.  Anywhere that I referred to a "tailcoat" with the words "frock coat" has been fixed!
