Embroidered long sheer tunic dress/ bathing suit cover up

Super sheer and light weight fabric. No designer label or fabric content tag. It has the feel of silk but is probably polyester. Colorful embroidery at the neckline and down the front. Embroidered cuffs and trim along the bottom front hem. Pull over. Deep side slits start at the hips. Solid royal blue front. Print sleeves and back. The only tag is 44. Must be a size. I'm listing under size M but please use measurements to insure a good fit. It measures 46 1/2 long. 15 across the top of the shoulders. 19 sleeves. Laying flat seam to seam it's 21 across under the arms, 19 1/2 at the waist. Excellent, like new condition. I ship same or next business day.
