I purchased this from the brand "saison de papillon" for ¥3,490. I think you'll be able to wear it comfortably with its cool-to-the-touch material ◎ Please feel free to contact me if you have any questions! The following is quoted from the website: ■ Features: A feminine pointelle and five-sleeve openwork summer knit cardigan with a stylish feel. It can be worn as a cover-up or as a single pullover. A sleek silhouette that keeps the upper body compact. The openwork knit with a flowing feel gently hugs the body line, creating a feminine, curvy line. The neckline is a feminine, deep V-neck that beautifully showcases the décolletage and enhances femininity. The sleeves are slightly long five-sleeve, subtly covering the upper arms. You can wear it comfortably even in the sweaty season with its cool-to-the-touch material. ■ Material: 63% rayon, 37% nylon ■ Colors: White, Purple, Black ■ Zipper: None ■ Lining: None ■ Sheerness: Slightly sheer ■ Fabric thickness: Thin ■ Fabric elasticity: Yes Country of origin: China Model: Rui [Size M] Wearing Height: 162cm B: 77cm W: 56cm H: 84cm
