Respect the rules
In traditional artisan craftsman terminology, a journeyman is honing his craft, no longer an apprentice, not yet a master.
Here, we define the journeyman as a guy who familiar with the rules. He knows to match his metals and leathers, leave the bottom button undone, and wear laces with suits. He probably owns some selvedge denim, a made-to-measure suit from an online 'tailor', and some colorful socks. He can hold his own, but he's still likely to make mistakes if he strays too far from convention. Making these mistakes, and learning from them, is how he graduates to the next level.
If this is you, go with a simple and classic tuxedo, and execute it with perfection.
