Cross dressing your ethnicity

My man walks in. He wearing a thobe, a long shirt favoured by Muslims, it has gold embroidery round the neck and cuffs. No collar. Brown open toed sandals peek out from below his shirt. He stands there silent swaying gently as if trying to take stock of the situation. He mouths a few words bu no words come out. I think he has finally lost it. Grabbing hold of the back of a chair, he steadies himself and tries to speak again. "I got myself arrested again. They've just let me out."
I'm past being shocked at this, my man and the police are on first name terms, he's one of their regulars, he has his own cell and they know he preferences for breakfast, except they don't serve his preference. Extra strong lager is not on the list.  Tea, coffee, toast yes but Tennents Super, no.
I had to ask. "What did you get arrested for this time?"
"I decked a guy." he is not his usual eloquent self, I'll need to dig it out of him.
"Why?"
"He didn't like my shirt."
"The shirt you're wearing now?"
"Yes." He rubs a hand across his unshaven chin then over his head as if bored. "I can wear what the fuck I like."
"Yes but...." I begin.
"He said I was disrespecting his religion by wearing this. I told him he was disrespecting his own religion by threatening me, he wouldn't leave it so I gave him a couple, one in the gut and as he went down another on his chin." he goes to demonstrate and has to quickly grab the back of the chair again, the swift one two was too much for him in his state. "I left him in the road" he continued, " and walked home. The old bill came knocking an I took a ride down to the nick."
"Are you being charged?"
"What do you think?"
"You got let off with a warning?"
"Booooom!"
"So matey boy didn't press charges then?"
"Apparently not, he called the police of course but then didn't press it."
"So why the shirt then?"
"Don't you start."
I dropped it. I guess we'll never know the secret of the thobe.
My man wanders off to find a proper breakfast in a ring pull can.
