I said this in another thread and while this isn't my favorite design,if you're not gonna have the trunks just making the belt yellow goes light years in making the design still work well.

I don't know what side of the trunks argument you stand on, personally I'm pro, but Action really does show how simple it is to make the costume work without them just by having the belt be yellow. And honestly I'd be mostly okay with that if they didn't always try to make everything all sci fi and tactical looking.
