I haven't bought too many premium jeans before so I would be glad to have some help. I'd like to buy a pair of Studio D'artisan, but which fits are "looose" Even if there aren't any, can you wear them loose by buying bigger size ? My normal size in jeans is 30 * 32, what size should I order if I want the studio d'artisan (from style ?) to fit loose, sort of like the levi's engineered does.?
