Made in Italy minimalist navy dress with golden zipper details

EUC. The label says XL but it actually fits more like M (loose on an S and fitted on L). Have never been an XL but I’d think it’d be way too fitted, even though the fabric have some stretch. The stretch allowed me to wear this dress multiple times when my weigh was oscillating and it always looked stunning. The sizing difference is likely due to international standards as this dress came from Italy (made and purchased in Italy during one of my trips to Europe).
