Most of my designs are either inspired by a detail I've seen around which I build a garment or they are an interpretation of a theme or idea someone has proposed. In this case, Cecchetti may somewhat fit the former category but in many ways it's an interpretation of a sort of nostalgia I feel for things that aren't so much a part of my life these days.
I'm a little bit bottom heavy (perhaps "pear shaped" is a more acceptable description) and I have always found drape neck designs, with their delicate folds of fabric framing the face, to be quite flattering on my figure, especially layered under the many suit jackets I no longer wear, now that I work from home. (I'm not complaining, working in my PJs with my dogs by my feet, beats looking fashionable, any day of the week.)
Along with the subtle drape at the neck (for which I provide notes in the pattern for modifying it to be more or less draped) I also tried to capture the aesthetic of the warmup clothes my classmates and I used to wear when I (long ago) took ballet lessons. I was amazed at how overly long sleeves and leg-warmers, would make one's extensions and arm placements look even longer and more graceful. Cecchetti has a little more ease than those pieces I used to wear, and the soft, decadent silk and merino yarn is surely not meant for sweating and leaping, but the vertical body darts, sleeves that slip past the base of the hands and the hip length all serve to elongate and flatter the body.
I think that people who knit this piece will find it very comfortable as well as flattering and very easy to modify as you go to get a good custom fit. As with most of my designs, it's knit seamlessly in the round, including the set in sleeves. And do not worry about it being all in reverse stockinette, the instructions allow you to knit it either right side (purl side) out or wrong side (knit side) out.
