A modesty panel is a strip of fabric that is tacked to the inside of one side of the back of the corset. When you put the corset on, position the panel over the gap and keep tucking it in as you pull the corset tight.
Modesty panels are made from the same fabric as the corset as standard, though other fabrics may be used - just drop us a line!
Some people like a modesty panel to keep the colour of the corset at the back or simply to cover the skin. If you are new to corsets, please bear in mind that it is perfectly normal for the skin to fold a little under the lace (many people like that bit!) and it can be fiddly to tighten the lace whilst keeping a modesty panel straight!
