I've been recently stepping up my game when it comes to my daily work clothing. I'm pretty good for suits in terms of colors, patterns etc. and although I've bought all kinds of variations of shirts I'm starting to realize that my pants are all pretty plain. After reviewing the shoe threads on here I've figured out I need a more diversified pant collection.
Does anyone have any advice on styles / colors I should be stocking up on? Right now my wardrobe is largely made up of 3 blacks, 2 gray, 2 charcoal and 3 tan / linen. All of these have no pattern on them and I prefer a flat pleat with a straight cuff on all my pants. My work environment is more relaxed than most but my day in, day out look is business casual and wear a long sleeve shirt (french or straight cuff), pants and when required a tie.
I've largely stuck to the darker colors but I'm not sure what the staples are to have in my wardrobe or what I should be looking out for. Input appreciated!
