Designed with comfort in mind, the side seams have been eliminated. The soft feel of the 100% cotton fabric is a key feature. The cotton is organic. 【Materials】 By using thinner threads and increasing the density of the fabric, we have created a delicate texture that feels good against the skin. In addition, by newly adopting air tumbler processing, which uses the power of air to soften the fabric without using water, we have achieved a soft and fluffy texture while also reducing water usage by 1 liter per garment. This product is good for both the wearer and the environment. 【Design】 The buttons extend to the top of the collar, allowing for a 2-way design that can be worn open or closed depending on the temperature and your mood. The waist is fully elastic with an adjustment opening, allowing you to adjust the fit by pulling out the elastic and sewing it in place. The elastic is not fixed, so it can be replaced. 【Specifications】 Transparency: Slightly sheer Fabric thickness: Thin Fit: Relaxed Waist specifications: Full elastic (with adjustment opening) Care Instructions: ● Dark-colored products may transfer color due to friction during use or contact when wet.
