Honestly I think John fucking rocks his windsock, and it's really kinda become an iconic look for him and Heir as a class.
Eridan also has some thought to invest in his fashion, and so does Feferi, but the others kinda... eh.

I especially don't like the base God Tier outfits. With the exception of Heir they all kinda just look like glorified pajamas. I wanna see GT outfits with some class, maybe a bit of rugged look, Knights having armor, that sorta thing.(Don't get me started on Bard's codpiece EUGH)

Im a big fan of nekromeowncer's god tier redesigns, check em out here https://nekromeowncer.tumblr.com/post/730280076151848960/ive-always-wanted-to-make-my-own-god-tier
