Elizabeth March/Missoni jacket/blazer

This beautiful blazer/jacket has me a bit confused. The main label is Elizabeth March, my guess would be a boutique store label maybe. I have not been able to find out much of anything about her. The most confusing is that the trim is Missoni as it has it throughout the print. It has no size tag or fabric content tag. It's a light weight fabric. The colorful abstract trim feel like silk. It does have a dry clean only tag. It has a 3 button closure with what appears to be shell in an oblong/rectangular shape. The color of the fabric is a dark denim blue or light black. Front pockets with the print trim on one side of the lining and the hot pink on the other. The print is also on the piping of the collar and down the front the back vent and cuffs. Listing as a size L but please use measurements to insure a good fit. It measures 31" long. 16" across the top of the shoulders. 24" sleeves un-cuffed. Laying flat seam to seam it's 19" across under the arms, 17" at the waist, 20" at hips.
