Jean Muir is renowned for her cut and use of fluid flowing silk like jerseys and this is a beautiful example of that. There are seams built in at each hip so the skirt has extra movement much like a thirties dress. The body is cut long and lean with vertical seaming and a belt to nip in the waist. Each seam is done with her signature top stitching in a matching red thread. This dresses would have been by one single person start to finish during this time period all of her pieces where meticulously constructed in this manner. It is really spectacular and literally transforms when worn. It has a definite thirties feel to it and the red gives it a little sense of naughtiness and danger. The sleeves are just wonderful they are cut fuller at the shoulder and upper arm and deliberately cut a bit long so that when the cuffs are buttoned the sleeves billow out above. Each cuff is 4" wide and top stitched as well. The original belt is present and features a unusual red tinted plastic slide buckle. Great condition and a fabulous and rare piece.
