This is a short-sleeved one-piece pajama from Tenerita. I have never worn it because I ordered the wrong size. Retail price: 17,600 yen (tax included) The following is a product description: Made with the highest quality organic cotton, this fabric is carefully knitted with a 36-gauge using two threads of 80-count fine yarn. The fabric created by knitting fine count yarn at a high gauge has a moderate thickness that can be worn all season long, and an elegant and delicate finish with a subtle luster. It has elasticity and a design that minimizes tightness, providing a comfortable fit that invites a good night's sleep. The light and skin-friendly short-sleeved one-piece can be worn comfortably as a single layer even in the hot season. Thank you. Season: Summer, Autumn Sleeve length: Short sleeve Color: Navy系 (Navy-based) Stains, tears, odors, etc.: None
