Liners, protection for the skin!
The liner for those unaware is a little tube of fabric that we use underneath the corset to protect our skin against the friction caused by wearing the corset.
Some people are more sensitive, and the liner helps prevent / reduce the redness that we in the skin by prolonged use of the corset, burns caused by mooring Cordone and in addition also protects the corset of our sweat for example.
In other words Liner's all good! And now they are available in the shop as well.
