Dark navy YAECA WRITE workers jacket in moleskin (75% linen; 18% wool; 7% cotton). From the 2013 A/W collection if I remember correctly. These are really hard to come by. Picked up in Japan but haven't worn too much because it's a bit too large for me (I'm usually a M in Yaeca items). Great colour, perfect cut and material feels amazing.

Length: ~69 cm
Pit to pit: ~56 cm
