By the Australian brand Rhythm, this shirt is in a deep purplish-blue made of rayon and linen for a nice lightweight fabric. The buttons add an elegant detail with their light tortoise color. (Surely, you can make it look nicer by ironing or steaming it a bit, I just do not own either.) Perfect to dress up or down: wear it open as an over-shirt for a more relaxed look, or buttoned-up for a more classic collar shirt vibe. I love this shirt but realized the color doesn't go with my eyes... It has been gently worn and has tons of life still in it! See photos for measurements flat. The fit is very slightly cropped.
