This is a Victorian style underbust corset, sometimes called a sports corset. Made from turquoise silk and brocade, it has a front busk fastener and lacing at the back. This corset is fully steel-boned and reinforced with sturdy cotton drill lining. The image doesn't do the stunning turqouise silk justice.
The waist size is 22", which will fit natural waists between 24"-26" comfortably and larger sizes if tightly laced. There is an intentional gap of approximately 2" at the back.
