Rétro 1960’s-1970’s high-end boho white shirt-rare authentic 1 owner vintage

This is a rare find. I bought many items from this French designer selling in posh French boutiques in Montreal in the 1960's and 1970's. I kept this one over the years because it had a relaxed fit and a timeless style. It is also versatile in style: you can tuck it in your bottom or not and you can up or down style it by pairing it with jeans or a fancy skirt or pants. The model wears a dark bra and you can barely see it thru the material so you could use a bra or a bralette as a pairing item with your bottom. It is labeled as a size small but it was also very nice on me, as a size medium. The live model on some pictures wears a size 6/8 and it fits her perfectly. Best for you is to look at the measurements below. You control the size of the collar with the tie strings at the front. Please see picture of label for material. Can be washed by hand. Spotless. Stored for many years in a blue garment bag (away from light and dust) in a pet and smoke free home. Measurements when flat and approximate: Shoulders are raglan so a non-issue Pit to pit: 21 inches Length: 20 inches Knackmixing ideas: see picture of live model being a stairs guard rail for pairing idea.
