18th century jacket ponderings.

So madamekat has been talking about this mythic Germantown 18th century event. Which sounds like tons of fun, the only problem being I've got nothing to wear!! It's only a few weeks away and I don't wanna go quite as crazy as I did for Belvidere...that was enough crazy for one year...but I'd really like to go. I think I can still fit the navy blue petticote that goes with my hand sewn 18th century jacket (ahh weight gain) but I'm 99% sure these sausages ain't fitting in those tiny sleeves. So I've been toying with making a new jacket. 

I found these two fabrics at Joanns that seemed...18th century ish to me. But I fully admit I'm going off of vauge aestetic here an nothing more specific than that. 



I'm thinking of a jacket like this one, or the one in Costume Close Up.
