It's a setting where wizards must strictly adhere to a dress-code

>It's a setting where wizards must strictly adhere to a dress-code
>Player wizard continuously flaunts the dress-code

Is there any way to fix this problem justly?

Have everyone think of him as just some random idiot. If he claims he's a wizard, they laugh at him. Other wizards refuse to help someone so obviously counterfeit.

Don't play Dragonlance.

Are you implying that would be a problem for most players?
They just have to embrace not being seen as a wizard.
Dirty hair and clothes, tattoos of spells on their bodies

Depends. What is the dress code, and why was it instituted?

If it was for practical reasons (robes that can easily be removed to avoid damage from being immolated), then practical consequences should follow (He gets immolated).

If it was for social reasons (Archmage gave his students a particular robe ages ago to show their superiority, now all mages wear it to imply such), then social consequences follow ("You're no wizard!").

If there's a dress code, then there should be a reason for it, and the consequences for ignoring it follow from those reasons.

...

play a low magic setting where magic is strictly a plot device.

Fashion cop battlewizards, of course.

Seconding this motion. Have them appear in a column of rose petals

I imagine them clothed like some of the wizards in Harry Potter, desu. Silly flashy colors that don't go well together, long robes and stupid hats.

This.

Some more thoughts:

Make it like when someone pretending to be in the army with fake medals or uniforms is caught and gets chastised by real soldiers.

Have the character have difficulty being taken seriously, like a grown man wearing a weeb t-shirt.

Have temporary stat penalties. Not adhering to the dress code? Your magic drill sergeant is displeased. Do 50 magic drills, guess what now you're character is suffering from exhaustion.

...wizard Diogenes?

Right. They're wizards, so their fashion appeals to other wizards, extra-planar entities, and people who can see the arcane runes on it due to having a high enough casting level

Have the Sharia police whom are immune to magic beat him up.

I'm confused as into why this is a problem, let your player be a snowflake. As long as he roleplays it well it really shouldn't be a problem

If its a setting where casting components are required have him be shoo'd off from components stores because he offends the other patrons. Other wizards mutter behind his back but powerful wizards challenge him to wizard's duels for his lack of decorum. Have the law hunt him down for being an 'unsanctioned' wizard.

That sounds amazing
>sitting at a lecture in a college of magic
>eating loudly
>using small spells to fuck with other students
>argue with lecturer
>they don't kick him out because he's better than everyone else

Snowflakes melt.

My players are doing X where Y will happen to them! What do?
>Have Y happen to them for doing X. Later suggest they do Z instead.

Give him what he wants and make him hate it. See all above listed social consequences - let him suffer several, but keep it minor. Too much adversity breeds stubbornness.

Instead, take away the novelty of his actions. He finds like-minded people who refuse to comply. Turns out they're mostly insufferable prats who are only bound by similar contrarianism - they spend more time arguing and backstabbing than they do bitching about The Man. With the authority, they mostly go along to get along. They may talk a good game on destroying the status quo when they're drinking ale in a cellar, but they'll never cast in the streets, and might well turn on him if he's dumb enough to do so.

Punish him for it, you'll make him feel like a martyr. Make him hate it, and he'll abandon it of free will, especially if you make compliance easy and the norm.

Have Rasputin kick his shit in

Stop being so anal, maybe? Why does it matter?

>archmage is pontificating
>wizard Diogenes lifts his robes and proceeds to take a steaming shit on his seat
>all the other wizards start scrambling to get away from him

Make this happen!

It's a dress code. If you don't follow it, the bouncer asks you to leave. Nicely, once, then curbstomps you if you're stupid.
