This is a Petit Bateau Marinière pullover. It's a classic French casual Basque shirt, but instead of a boat neck, it's almost a crew neck. It also features a supple yet tough cotton material that doesn't feel stiff. The neckline and hem slits are neatly reinforced on the inside, and the construction is meticulous. It's the classic navy and white color, but the striped tab on the hem adds a cute accent. The size is L. Measurements: Width: 51.5cm / Shoulder width: 46.0cm / Length: 70.0cm / Sleeve length: 68.0cm Men's sizes are hard to come by, so if you're looking for one, don't miss out. I bought it, but the size doesn't fit me well due to changes in my body shape, so I'm selling it. It's been worn only once or twice and is in very clean condition with no stains or damage.
