>>36330332pokemon has always toed this line of not-too-serious and not-too-childish. Ive never watched JoJo so I cant comment on the direct comparison, but just looking at the pic I would say Archie and Maxie's outfits are not as wild as the JoJo outfits. And again, I would say Maxie is not dressed as 'crazy' as Archie is.
At the least, the outfits make sense for their characters, and even add more personality than the RSE ones. You may not LIKE the personality they added, but its definitely more than we got from their characters in RSE.
