My personal favourite. Tailoring was key, and subtle gathers and shirs replaced the ruffles and frills of the early 30s. Sleeves were set-in and slim fitting, and often had puffed shoulders, which developed into square shoulders as the war progressed and man-tailoring became more fashionable. Skirts were flared and swingy in the late 30s and early 40s, but narrowed to a slim A-line by 1946 due to fabric rationing. Hemlines rose over the same period to around knee level.
