There is a great deal of hand finishing in proper haute couture garments - it can take ages to finish a garment as the inside should look as good as the outside - nothing overlocked, all French seams, silk linings and hand made buttonholes. I loved studying couture techniques but a couture garment is not something you can knock out in a couple of hours. The thing that annoys me about SB is not giving them enough time, and then the judges moaning about it not being finished, and then waxing lyrical about something that looks quite shoddy to me. If you want to see couture garments being made there is a Chanel YouTube video about the inside secrets of an atelier- it’s amazing the detail , hand beading etc.
