The fabric is not stretchy, creating a moderate gap between the fabric and your skin. This means they look quite large, but they are designed to prevent them from flipping up or digging in. Outer fabric: 100% Cotton Lawn, Mufan Lining fabric: 100% Cotton Double Gauze (checkered pattern weave) Approximately 80cm of elastic is threaded through and loosely tied, so please adjust it to your own size. It stretches up to about 100cm. The waistband has three elastic bands for a stable and comfortable fit. For your reference, if you find them too tight, removing the bottom elastic band will give you a feeling of freedom, as if you've sized up. For hygiene reasons, the fabric has not been pre-washed, so please be aware that it may shrink slightly. We recommend washing them in a net. Please be careful as dark colors may fade. We put our best effort into making these, but they are handmade by an amateur. There may be slight distortions in the fabric or stitching. Please consider this before making a purchase.
