"Vogue Sewing" c1982, features a few couture techniques in Chapter 9 (The Custom Touch). It discusses the hidden details that distinguishes a dress from "The Dress". These distinguishing details include: underlining, lining, hand application of a zipper, bound buttonholes, inside waist stay, foundation supports, fabric stays, weights, (covered snaps, hooks, eyes, and buttons), hong kong finish, hand-rolled narrow hems, etc. There are some sewing and design fasionistas that feature haute couture sewing techniques on their blogs. Here are a few links of interest:
This fall Erica B. and Laura created beautiful Chanel jackets. Belinda's Sew 4 Fun as an excellent tutorial on bound buttonholes. And the Sewing Divas have several posts on couture sewing: Haute Couture and Couture.
Haute Couture - "To me it means only 2 things: (1) A particular and very specific type of business model for custom clothing manufacture unique to France, where it was invented and still maintained in a much diminished state from its heyday in the 1950's, and (2) it's a particular type of sewing that primarily uses hand sewing for most of the garment construction . It does not apply to: accessories, home dec, cosmetics or anything made in a factory."
