Milly Cascade Sheath Dress: Chestnut. Asymmetric V neckline. Sleeveless. Cascading ruffle down front side. Front slit detail at hem. Asymmetric V'd back. Polyester/viscose/wool/elastane. Made in Italy of domestic material. Original price: $360. (Neiman Marcus, Bloomie's, etc.) I really like the way it is styled in the second photo - it looks like it would make a great transitional garment for summer/fall & winter/spring.)
I have a piece of fairly drape-y light brown poly/rayon plaid (no lycra/elastane, though) I bought at Fabric Place in Framingham, MA that I'm planning to use. I'm not sure about the full-length ruffle, though - on the one hand, it creates a slimming vertical line (good) but adds bulk over one side of my already-bulky boobs (not so good). I'm thinking of just having the ruffle go from my waist to the hemline instead, sort of like the Anthropologie-inspired skirt, but in a sheath dress version.
I'm going to use my Unique Patterns dress pattern (9023U0) as a starting point, changing the center front from two pieces (with a waistline seam) to one, rotating the bust dart into a princess seamline, putting in a side seam (invisible!) zipper, and, of course, changing the front and back necklines and adding the flounce cascade. I should probably line it, too, so I could wear it over a brown turtleneck top as a jumper.
Easy-peasey, right? I'm going to work on drafting the pattern tomorrow, cut out a muslin Thursday and sew that up on Friday afternoon. With any luck, I can get started on cutting out the real fabric early next week.
