just like when you are big in terms of weight certain styles just don't become you.
when you are a tall dude some of these styles you have to pass on. Because they just don't become you.
I'm sure Lebron could have hollered at a bespoke tailor who could have whipped up 7 beautiful suits, of some great summer weight wool, blends or linen. He would have been looking like a million bucks for the finals.
If he has a stylist and they picked that outfit! He should fire them.
If he doesn't have a stylist he should get one!
