The embroidered initials, probably Rhett Butler, don’t you think? This would look great on a lady or man. This shirt is a Kohinoor label from the 1940s. I believe the size is very close to a modern 15 ½ as it fits my grandson perfectly and that is the size he wears. Measures 17 inches across shoulders, 18 inches across chest, 17.5 inches across waist, 30 inches from top to bottom and the sleeves are a generous 25 inches long. Keep in mind that vintage shirts are more tailored than our cookie cutter designs today. The condition is very good with only minor signs of wear. Each sleeve closes with 3 buttons, one side is missing two but one is inside the pocket, so you are only one short.
