Here’s a garment so vintage I had to look up what it was before posting; a pelise was a mantle worn over an outfit for additional warmth and decor. Though usually floor-length, this appears to be a shorter pelise, which came into fashion for a bit in certain parts of Europe. Its modern descendants include the overcoat and the dressing gown. Also whatever you call that thing you wear at night over your nightgown; I can’t recall the name at the moment.
Rather oddly it suggests this pattern would be great for a baby on the left side, but a quick assessment of the measurements indicate it’s a 32″ bust- a little on the small side for the fully-dressed modern woman, but certainly too big for most toddlers. If you’d like to create this in a larger size it would be easiest to up the gauge from the wee 7.5 sts per inch to something more reasonable like 6.5.
