This is an ACOS long-sleeved winter shirt (size L) for Yowamushi Pedal. I bought it a long time ago for a different character and it has been stored unopened and unused. The original bag has deteriorated, so I will repack it in a new bag for shipping. If you're looking for a light blue long-sleeved dress shirt, it should be perfectly fine. The fabric is sturdy. Feel free to ask if you have any questions.
