I quite liked that Ultimate Spider-Man suit posted a page or two ago after having already seen it before.
I think the simple web pattern works extremely well and it allows for black webbing to be uses without the suit looking too busy. I love the shiny spider emblem too. It's probably the perfect suit (to differentiate Marvel's from the other two/three incarnations) IMO but as others have said, it would benefit from texture. Also, I don't like how the Ultimate suit is missing the arm stripes; I feel that's an essential part to the red and blue suit, even if they're really thin, like in both TASM suits.
Anyway, I did a manip of that suit with some texture (some random hexagon pattern I found on google images):
It's likely that the MCU suit will be their own take but still look professional and aesthetically fit in with everything else going on in that world. As other users have said though, they need to make this one-piece suit work in this world.
