The Size and Measurements included are not the measurements of the garment itself. They are the 'recommended fit' measurement depending on how wide you like the gap in your corset to be and how tight you personally prefer to lace your corset.If you are unsure on sizing and fit then feel free to send me a message with your measurements so I can advise you. Alternatively, you can buy a piece off our 'made-to-order' collection to ensure a piece be made to your exact personal measurements.
