This is a classic Basque shirt from MONT KEMEL (モンケメル), in white and black. I purchased it from HugHug around October of last year. It is still currently on sale. This item is new and unused. Size is 36. From MONT KEMEL, this is the BASQUE SHIRT BORDER. Made with 100% cotton jersey fabric, it's a basic item with a moderate thickness. The overall oversized design makes it suitable for layering under a jacket or wearing on its own. It's a simple yet carefully crafted item, with details like side slits at the hem and reinforcing fabric on the left and right necklines of the boat neck. It's a popular, classic cut-and-sew item that's in demand every season.
