Beautiful reversible Lululemon quilted vest size 6(?)

This black vest does the impossible. It’s warm but also flattering. It is completely reversible, though the pockets are only available when wearing it belt-side-out. The asymmetrical zipper and collar are very stylish. It is in excellent shape with no stains, rips, or defects. I suspect it is a size 6. It measures 17” across from armpit to armpit, and 23” from neck to hem. Since it is Lululemon and the size tag is gone, I can’t verify that it’s a 6 but if it’s an 8, it fits very small.
