There must be hundreds, if not thousands, of lists at this point on how to build a basic wardrobe. Most are meant for people who are just starting out, so they include very basic things such as a blue blazer, a dozen dress shirts, two pairs of dress shoes, and a couple of grey trousers. Helpful if you’re still being introduced to this topic, but not terribly useful if you’ve been interested in clothes for a while.
There are a few exceptions. Here are three, written by men who have a lot to say on the subject of classic men’s dress. Be forewarned: this is not a short post, and these are not short lists. These are also meant for men who are either interested in clothes or have significant means. I think they’re enjoyable to read, so long as you take them for what they are.
