I purchased this item from the official website and tried it on indoors. I washed it once, inside out, in a laundry net. It's a very lovely item, and I hope someone who fits the size will buy it. The following is quoted from the website: 【Features】 ・A gentle tapered silhouette that makes your legs look beautiful ・Of course, the silhouette is beautiful, and the elastic waist makes it easy to wear every day ・One pleat prevents the waist area from looking tight ・Uses NASA-developed "Outlast" fabric ・Excellent functionality that adjusts the temperature within the fabric on hot and cold days ・Sewn at an angle that makes it easy to put your hands in the pockets ・"9 ounces" that can be used all season ・The fabric has stretch (2% polyurethane), so it's not tight even though it's slim ・Designed to avoid a baggy length (length) to consider the volume balance with shoes ・The secret to the sharp silhouette is the size and tapered silhouette 〇Recommended for people who: ・Want black pants with a perfect silhouette ・Don't want to wear a belt ・Want a slim silhouette even when putting things in your pockets (one pleat) ・Want comfortable temperature regulation (Outlast) ・Want details that make your feet look beautiful no matter what shoes (sneakers) you wear ・Want simple-looking pants, but with attention to detail ・Want to be able to wash them in the washing machine →Both normal wash and delicate wash are acceptable ※ Washing "inside out" prevents color fading Size…Waist (rise/stretch cm) x Thigh (cm) x Hips (cm) x Inseam (cm) x Hem Width (cm) M…75/89 x 30.2 x 102 x 71 x 16.5 (approx. 30 inches) ■Material ・Cotton…57% ・Rayon…41% ・Polyurethane…2% ※Uses Outlast fabric ■Weight 449g (M size) ■Country of origin Made in Japan ※Although unused, this is only a personal inspection.
