I'm not a fan of the red hip patches either. I think the manip posted a couple pages back is the best variation (outlining the MOS belt with red). if you are going to ditch the trunks, don't add red patches. just make the traditional yellow/gold belt more prominent. It does the task of breaking up the blue perfectly. The whole point of getting rid of the trunks, in my opinion, based on the other design elements of the MOS suit, is to give it a modern, futuristic scifi unitard aesthetic. Unitards are used in scifi because they look practical, seemless, and beyond fashion. They are traditionally visually an indication of a society that has evolved beyond vanity and focuses on utility and function. Ditching the trunks plays upon that aspect of Superman's character and Kryptonian heritage. Don't undermine it by adding poor substitutes for the traditional trunks.
