Not so much a custom as a temporary "how would it look"

[UnderdogDJLSW]

I had some large burgundy ribbon from the holiday, and decided to see what some shorts would look like on movie Supes. The edges are shredding too much to use that sample, but I may look for some burgundy spandex at some point.

Welcome to the Pro-Trunks Club!

I think he needs 'em, if for no other reason than it breaks up that massive field of blue and balances the color scheme. High collars, fancy trim and lack of belt and trunks might be fine for a regal, aloof character floating above the crowd in judgement, but not for Superman. He's the humble, two-fisted, "fair play" boxer of the DC universe. A quintessential strongman. It's a classic look, DC! Embrace it!

(Maybe I should have just said "looks good", which it does. Sorry, I struggle with the whole "brevity" thing!)
