This is a long-sleeved pajama set for women from Wacoal. The size is L. It is new and unused. Please note that it does not have tags. Although it's long-sleeved, it's thin, so it's perfect for wearing in air conditioning. You can wear it in the current season or even in autumn when you no longer need air conditioning. If you have any questions, please feel free to comment. I will carefully pack and ship it to you.
