We use pre-dyed Eurasian linen that has been washed in with a moderate thickness (1/40th). These pajamas are made of 100% high-quality linen with a plump texture and a comfortable touch. The orthodox windpane check and thick black piping tape add a touch of adult cuteness. Pajama pants have side pockets for convenience. All the stitching parts, such as the sides of the body and the armholes, are folded and sewn up, so they do not get caught, are not frayed, and are durable. The brand tag avoids the neck and is subtly under the front body. All pajamas come with a bag made of the same material (H34×W30) for convenient travel. Since it is an elegant top and bottom, you can wear it as an outer jacket or pants. Please avoid tumble drying when washing. When ironing, the firmness of the fabric returns. Due to the nature of the fabric, it will shrink slightly, so please consider the size selection.
