I am making a jacket with dropped shoulders and am wondering about how to achieve the best fit. There is much info about set in sleeves, but so far the only thing I have found regarding the dropped shoulder is how to determine and alter the sleeve length in an article by Louise Cutting I haven’t even been able to find a good picture of such a sleeve from the side as garments are seldom photographed to show that area specifically. How much should a proper shoulder seam be dropped? How much extra room should the bodice have to allow for proper installation of this kind of sleeve? How do you know how many “folds” are enough around the upper arm? What other details do you look at to determine if you have the proper fit/appearance in this looser type of garment? How do you alter these details should that be necessary?
Thanks so much for any information any of you can impart.
