@Link327 it's related to clothes detail. Melee introduced overall pockets that are behind Mario, and Brawl retained them but Smash 4 got rid of them probably to avert the player gaze.
How dare you Sakurai, how dare you you remove the backpockets from Mario. Every Smash game released after Brawl is now a disgrace as Mario does not have backpockets in them. I can't believe you did this, I thought you put tons of effort into you're games, but no, you just had to remove the backpockets didn't you? smh Sakurai, you should be ashamed of yourself
Sakurai's overwhelming nerf can be seen in the Mario series afterward because even when Odyssey reintroduced more realistic denim, they didn't include the elusive pockets.
