This is a pajama set, a top and bottom set of nightwear. My family purchased it at a store as a spring/summer item, but they said they won't be using it. It's a cotton-blend material, so it feels soft to the touch and seems comfortable. It's new and unused, with the tags still attached. 【Material】Polyester 72% Cotton 28% 【Color】Navy系 (Navy-based) 【Design】Polka dots + geometric patterns 【Condition】Unused 【Size】Men's M Chest 88-96 Height 165~175 Thank you.
