The women’s tailored jacket is a tricky piece to make as precision is of the essence. When a tailored jacket is examined closely, the two elements that really make or break it are the sleeve and the collar, and the way these two elements are assembled. Forgetting the design dimension for the moment, if the collar and sleeve are well assembled, the jacket will look professional from a technical point of view and will allow the piece to sit well on the body. The hang of a jacket is the key to its success.
