This is the Lowell Mill dress, by Past Patterns. I shared its construction earlier, but finally I have some nice pictures. It really was amazing to sew. The fabric was lovely, and it was the first time I have done leg o' mutton sleeves. Much of this dress is topstiched, and a garment becomes so much more dear after hours spent handstiching.
The Pelerine is the only thing that varies from the pattern. I copied it from a gown in the Tasha Tudor collection. In my opinion it's extra large scallops are striking.
