Neck... Crew neck/U-neck Thank you for looking. I have worn it about twice. Please refer to the image for the material. I have checked the condition carefully, but as this is an inspection by an amateur and stored at home, there may be oversights. Please understand this in advance. Please only purchase if you understand this. Please refrain from purchasing if you are sensitive. As it is stored at home, please refrain from purchasing if you are concerned about minor details. I will fold it compactly for shipping. Please understand that there may be folding creases. Thank you. Cancellations and returns after purchase cannot be accepted. Please understand.
