mixing brands

[NaturalWonder83]

im very confused

with sports clothing, like nike shorts, and under armour shirts, etc

what is the right way to mix brands?

does it look dumb to have a nike shirt on, and adidas shorts?
or should u wear all the same, like full under armour?
or what about nike shirts and shorts, but plain white socks and just any old sneakers? etc

I think mixing brands shows you are a confident person who is not trying to hard to have on a specific "outfit."
