Vintage early 1960s button front cardigan size medium

This cardigan is absolutely gorgeous. It's a beautiful light eggshell/sky blue (the last 3 pictures before the photo of the brand tag give an accurate depiction of the item's actual colour) with a printed design on the front. It's almost 60 years old and is in beautiful condition. I can see wearing this with a beautiful flare skirt or cropped skinny jeans for a perfect 1960s look. Fabric tag is missing but it feels like a dense acrylic or even a wool acrylic mix. It's not scratchy though. There is some very slight pilling throughout but it's hardly visible. This would be normal wear for an item of this age.The last few pics show the worst of it. It's also missing the size tag but the flat measurements below suggest it's a medium. If you`re unsure, please compare the measurements below with a similar item in your closet. Flat measurements in inches: Armpit to armpit seams: 19.5 Waist: 18 Hips: 17.5 Sleeves: 20.5 Length: 20 Colour of item may vary slightly from pics due to differences in device screens and lighting. I reuse packaging as much as possible in order to reduce waste.
