I was extremely lucky to have been taught by 2 traditional tailors & a couture seamstress. I didn't realize for a long time that the techniques they taught their students were unusual in the current quickie "make it in an hour, e-z pattern" world. I think it finally hit me when I went through the instructions of a "very difficulT" rated Vogue pattern & mentally said "ok, cartridge pleats, customized fitting, interlining, etc, whats the problem, I do these all the time". Threads magazine, years ago, did an interesting comparison article on a commercial "retro" pattern. They had someone sew 2 identical dresses, one with the techniques that would have been used on that type of dress in the 1950s, including a waist tape & interlining; the other with the modern shortcut techniques in the re-issued pattern. They then compared the results point by point. The old-style techniques won hands down!
