This is a Ralph Lauren shirt. The size is 10, which is equivalent to a Japanese size 150cm. It can be worn on its own or as an outer layer. It's also useful in the summer in places with strong air conditioning, so you can use it all year round. It's a used item, but it hasn't been worn much, so I think the condition is good. Individual perceptions may vary, so please purchase if you are not concerned about minor details. Please note that there may be wrinkles from storage, and it will be sent in simple packaging. Please refrain from price negotiations.
