Also, they removed the belt.

I don't like these kind of full spandex suits.

They are pretty much standard in the industry. You must not like a lot of superhero costumes then.

They were cloth, originally.

From an art pov, it's just lazy. They don't have to bother drawing clothes, it's just body paint.

Oh god wtf is that design. Look what they did to my boy :(

He kinda looks like Jack Knight

Reverse the red and blue, except above the S Shield. Make that black. Then, I think it would look pretty cool. As it is, I find that it looks weird.

I still prefer black-red color scheme for Superboy's suit like the one from Earth-15 or Lego Batman 3.

Low key could be a banger, although the black T-shirt would always remain the more popular look

Connor's black t-shirt and jeans look always feel kind of boring and under-designed to me.
