Crochet, asymmetric halter

This pretty dress is a bright school bus yellow. There are no fabric tags but I’ve been working with fabric my whole life. This is that beautiful light thin Indian cotton in the skirt. The top crochet is at least 50% cotton. It may have a little poly in it. There is a small elastic box that allows that pit pit to stretch easily to 20 inches.there’s no tags in this dress for sizing. I’m going to list as a medium or large. A symmetric ham with a ribbon added on. In excellent condition light and breezy for summer.
