I strive to make my customers happy and deliver only the best customers service as possible. If there is ever a problem with an order, I will do my best to assist.My apologies ahead of time if that were to happen. Item is measured with fabric lying flat, unstretched. I use a Soft Tape Measurement Sewing Tailor Ruler for measurements to acquire the best accuracy. Some clothing may have a few wrinkles due to storage nothing major. I have size charts posted in the LAST picture of measured items.
