Vintage Blue Black Long Sleeve Button Up Size Medium

I love how vibrant the blue is! The sleeve have a button so that you can roll the sleeves up-you’ll are that pictured. It’s a light and soft material. The material tag is gone so I cannot confirm it but it feels like a cotton/polyester blend. The size tag is missing but this would be most appropriate for a size medium Underarm to underarm approximately 25.5” Length approximately 27”
