This is a GANNI lace knit vest purchased at Tomorrowland. It has a collared V-neck and a back pleat, which makes you look slimmer. It's a short-sleeved fit for a typical size (see image 1), but when laid flat, it's straight from the shoulders, so the length will vary depending on your shoulder width. The hem is decorated with beads. The size is S/M, but it was sold as free size at Tomorrowland, and I think that's accurate. Length (excluding bead decoration) Front: 77cm Back: 80cm Bead decoration length: 2-4cm (uneven/see image 4) I cut off the sewn-in tag, so I'll include it (images 5-9). Thank you for looking.
