Chambray Shirt Blouse Button Up Fancy Back (L?)

Chambray Long Shirt . Pretty in the front and has buttons in the back. Lighter blue in person. Very feminine , soft well tailored . I don’t remember the brand as I almost always take the tag out of my tops. I normally buy L-Xl. Additional measurements on request. I believe I’ve only worn it once over a tank top. it’s been washed and is ready to wear .
