The list is a stupid, not funny joke.
Sweat pants you can wear until about 30, and if you have a big butt to show off.
Backwards baseball cap makes you look like an idiot at pretty much any age.
40ish for a speedo if you at the half a percent that can bull it off. Guys with darker skin probably 45.
Same with skinny jeans. A friend of mine is 33, look 20. If you have a small build then really what is the probably with skinny jeans?
What's wrong with earrings? If they are little and not numerous I see no probably with them for almost any age.
