I'm sure a spider-suit with webs that actually looked like webs would fit too. And red soles instead of silver wouldn't hurt the perfect fitting either.
I was going to say a little child, but teenager can be close enough. But then again some teenagers could have made a spider on the back in such way the didn't have to make an ugly indentation in the red zone to make space for it. Or maybe could have used a red spray over the soles.
I'm all for realism except when things look bad.
But I'll give you that at least in the trailer the suit's colors and texture looked great. And yes, he did move good. But that doesn't have to do with the suit.
