Vintage linen flowered long jacket

Not sure if 'jacket' is the right term. Nor indeed am I sure about the 'vintage' thing. Basing that on the shoulder pads and just the general look. It's a beautiful black linen long 'covering' shall we say, with a lovely embroidered flower pattern down the front. Closure at the top via a little clip (which could probably use a stitch or two for reinforcement). Brand name 'david n' which means nothing to me. Size 8; measurements in photos. Quite a lovely piece!
