Learn the rules
In traditional artisan craftsman terminology, an apprentice is just starting out.
This is a guy who hasn't put a lot of though into his wardrobe in the past. He's not used to getting dressed up, he doesn't know all the rules, and he's just fine with that. He has different priorities in life, which is perfectly understandable. Now though, either by his own choice, or by necessity, he needs to learn how to get dressed right.
If this is you, start by educating yourself a bit on the basics. Below are a couple of good resources. If you don't have time for that, not a problem, come see us, we'll take care of you.
