Curious

Does anyone know if he will ever change his main outfit or dye his hair a different color than blonde? I know it’s his iconic outfit and he’s an alien that doesn’t care abt that grooming or fashion but I’m kinda sick of seeing the tattered worn out suit and seeing that his roots have grown in. It does suit his personality but I was just wondering, like would he just have this suit (not including pajamas) for the entire story
