These are pants from Japan Blue Jeans. The size is 30. The color is a very dark denim blue, with the third photo being the closest representation. They don't look very "denim-like," so I think they can be used for business casual wear. My family member wore these. They were worn a few times and are in good condition, but please understand that they are used items.
