So there’s a thing going around that says “the sluttiest thing a guy can wear is more clothes” and this is not wrong. But context is important. Because we have to also consider the “commit to the bit” side of it.
In normal life, normal days, wear the button up and the sweater vest and the suspenders. Just wear everything.
But if you’re going to a con, the thing that will get you the most attention is going as hard as possible. Wear the most intense cosplay you can find (and don’t make a joke of it).
This is why, in the Mister International pageants the men with the capes and sparkles and headdresses are so much more impressive than the men in the three piece suit.
Usually the three piece suit would win over a loincloth any day. But paired with the feather headpiece and the flowing cape and the chest armor that would protect no one, the three piece suit loses because everyone else is also on par with the cape guy.
