Vintage 70s Satin Bolero Jacket

Picked this up from an antique shop a few years back, very cute find! The tag doesn’t say the size, but fits a US women’s 2-4. I did some research on the brand and label, and it looks like it’s from the 70s, though I can’t be sure. Here’s a link to the site I used: https://vintagefashionguild.org/label-resource/lanz/ The jacket is in great condition, with no stains or holes
