A man with a cowboy hat and a gentleman with sunglasses on his head are seated next to each other.
The very differently dressed men sit next to each other
It is possible that the men could be dressed similarly since they could both be wearing cowboy hats and sunglasses.
Just because one man wears a cowboy hat and one wears sunglasses it doesn't mean that they are very differently dressed.
Then men may be dressed or nude; if men are dressed they may differ in their manner of dress moderately or extremely or minimally or some range therein so they may not necessarily be dressed very differently; or men may wear clothing that is similar but may be wearing other apparel that differs.
