(Keep in mind that this theory is almost entirely a joke :)
Ok, so everyone has been speculating about Luka, and what he might be like. He and Kagami are people who sorta attract Marinette and Adrien respectively. We know Kagami and Adrien's friendship began because they are both into fencing. But what about Luka? Well, many people are theorizing that Luka could be into fashion, like Marinette.
So this brought me to this conclusion:
COULD LUKA ACTUALLY BE STYLE QUEEN?
(Lol, let me know what you thought of this joke theory)
