Ryohin Keikaku Co., Ltd. (Headquarters: Bunkyo-ku, Tokyo; Representative Director and President: Satoshi Shimizu), which operates Muji, will sequentially launch the "Smooth Satin" series from April 20 (Monday) at Muji stores nationwide and online stores. Ryohin Keikaku aims to create a "pleasant life and society" based on the value of "simplicity that does not feel inferior to luxury," providing products and services that organize and enrich daily life. The new "Smooth Satin" series features loungewear and innerwear made from 100% natural lyocell satin fabric, characterized by its smooth texture. Because these are items worn for long periods every day, we focused on material and comfort. The smooth, skin-melting feel is comfortable, enriching relaxation time. ■ 100% natural lyocell material Uses 100% natural regenerated fiber lyocell, made from wood pulp produced under sustainable forest management. It features a smooth texture and excellent moisture absorption and release, making it comfortable to wear even in hot summer months. ■ Seamless sides for minimal sleep disturbance (pajamas only) It is said that people toss and turn about 20 to 30 times a night, so pajamas are designed without side seams. This design reduces discomfort in areas that easily touch the skin during sleep and minimizes the bulkiness of seam allowances, thereby reducing sleep disturbance. ■ Tops and bottoms can be purchased separately In response to customer feedback such as "I want short sleeves for tops but long pants for bottoms," we have added long pants, pullovers, and pajama dresses to our lineup, in addition to top and bottom pajama sets. They can be purchased as a set or individually. ① Women's Smooth Satin Short-Sleeve Pajamas This short-sleeve top and short pants set is light and comfortable for hot summer days. ② Women's Smooth Satin Long Pants Straight silhouette with pockets on both sides. Features a delicate elastic waistband for a relaxed yet elegant impression. Can also be worn as loungewear with individual tops. ③ Women's Smooth Satin Short-Sleeve Pajama Dress A-line silhouette with a light construction that allows air to flow through the garment. A cool and elegant piece for comfortable summer wear. ④ Women's Smooth Satin Flare Shorts The elastic waistband is wrapped in the main fabric, so it does not directly touch the skin. The gusset is double-layered, with 100% cotton material on the skin side. ⑤ Women's Smooth Satin Flare Tank Top A softly flared silhouette that does not cling to the body, recommended for hot weather. ⑥ Women's Smooth Satin Slip Dress Recommended not only as innerwear but also as homewear. The strap length can be adjusted with shoulder adjusters. Because it is made of satin, outerwear slides smoothly, and it is also characterized by not feeling bulky when worn under dresses.
