I didn't specifically make anything to be a costume to match a doll, but I used to do 18th century interpretation, so I have some things I made from that. It was pretty time-consuming stuff copied out of a book called "Fitting and Proper," which is charts someone drew based on 18th c. garments in the collection of the Chester County Historical Society.


I've seen people who've gotten some very good results from Butterick's "Making History" series, though I've never gotten around to using the patterns I've bought from them yet. Because of the popularity of Civil War reenactment, it's especially easy to find good patterns for all kinds of Addy-era outfits.


I don't know how into historical accuracy you want to get, but these sites have some pretty good patterns and a few also have some more generic ready-made goods:
~I like Townsend's site for 18th century and early 19th- they also have good ready-made goods, "accessories," and costuming books:

(scroll down and click on "clothing patterns")
(this site definitely has some kid-sized patterns, too)
They have an empire-waist dress pattern that looks like it would make a very good facsimile of Josefina's Christmas Dress here:

~Ready-made stuff, mainly 18th century:

(items on site are expensive, but give good pictures, esp. of shoes, so you can find modern-day substitutes)

This may be an HB member's site, I don't remember... but I bookmarked it a while ago because the person has done a lot of costuming and has a lot of photos of finished work, but a lot of the things are hand-drafted patterns based on those in costuming books. She gives a really thorough idea of the work involved for period-accurate stuff, and also includes a few easy-to-follow patterns for various small things.

Oh, and something to note: It'll be easier to pick the earlier characters if you want to go for the matching look, since girls' clothing was still pretty much just small versions' of women's, with maybe some allowances for length. Especially in Samantha's time, though, you'd be old enough to be wearing the outfits with the longer, slimmer skirts, and knee-length skirts like Samantha's would be inappropriate.

And Felicity's movie took a lot of liberties with headcoverings, or the lack thereof. Colonies further north, at least, tended to be a bit more strict with dress, especially with headcoverings and social judgements based on hair being left loose.
