Thank you for viewing. The size is 3, which is equivalent to a size L. I wore it a few times and washed it at home each time. The following is quoted from the brand website: This is an all-in-one garment that combines a top with a unique firmness and a beautiful surface created by high-density knitting, and bottoms with a distinctive firmness and texture. It's convenient as a complete outfit in one piece, and it also pairs well with other tops, making it a recommended piece for the spring and summer seasons, allowing you to enjoy various styles. The top has a slightly relaxed silhouette, and the bottoms have a tapered silhouette, making it suitable for neat and tidy coordinates. ■ Country of origin: China ■ Material: SHELTERING WHITE×T/C SMOOTH JERSEY (90% polyester, 10% polyurethane × 60% cotton, 40% polyester)
