I cut and sewed the size four with no alterations. I like that the pattern size is so close to ready to wear sizing! I used a cheapy fake silk from Joann Fabric. I spread my work out over the course of a few evenings after work...there is a lot of hand sewing (sleeve hems, bottom hem), and I didn't want to lose patience.
I will absolutely sew this again and hopefully improve the wonky parts. Oh, I used colored snaps instead of sew in snaps in the back closure. To accomplish this on such a thin fabric, I did interface the back facings per the advice of some others who had sewn the Sencha. I'm glad I did.
