This blouse is twice as versatile, on or off! The following is quoted from the website: ・UV protection ＊Functionality may decrease depending on the environment. ・Difficult to see through ＊Functionality due to the specifications of the lined parts (lined only on the front and back body) ・Machine washable ・Easy care (wrinkle-resistant) We've made it a simple design with a subtle, small random dot pattern so it's easy to match with your skirts and pants. It's packed with features, so we highly recommend it to everyone starting a new life!
