The healer gear was going to be feminine regardless since it's Rosa they are basing it off of. Albeit a bit more tame since her outfits were skimpy in FFIV. Less so in After Years. And Rydia is a fan favorite so her attire will mesh well with both Lalas and general females for Child Rydia, Adult Rydia and the Maenad clones which were low key clones of Rydia.

I don't think it will look good on males but you could go for a nice Wizard look with proper dyes.
