This came in a box of treasures gleaned here and there by someone who knows what I like.
It's a ladies blouse, all pleats down the front, linen calling for an hour of careful ironing using a pressing cloth to prevent shininess.
Not going to happen. Based on the tag I'm thinking it's quite vintage, but still heading for dismemberment and the dyepots. It has some exquisite details. Aside from my rude handing in the washer and dryer, it's flawless. If you'd like it as a garment, let me know and I won't chop it up. But you are going to have to iron it yourself.
