This is the dress I shortened to make ruffles for the samba dress. The blue swoops are the former armhole facings of that dress. I really like the way they curve across the front of the dress, kind of lifts it a bit. They're just pinned at this stage, when I get a chance I'll stitch them on. I might use some fusible webbing cut into strips (partly because I'm cheap, partly because I don't want to make it even stiffer, what with the original vilene already in the facings) to secure them before I sew, if I think the fabric can take the heat of the iron. Most polyesters are far sturdier than you'd think, but this one is unusually delicate.
