These are navy INCOTEX slacks. They are a straight-leg model. INCOTEX, which sells for more than double the price of typical slacks sold at select shops, is a model that clearly feels high-quality, including the lining. By the way, I bought these at BEAMS. The size is 48. These slacks alone cost around 40,000 yen, so if you are interested in INCOTEX, please give them a try.
