Link's blue tunic/champion's tunic in Breath of the Wild is the first thing that popped to mind. SS Zelda in Skyloft, and Skyloft clothes in general actually are nice too.
my fave Zelda outfits are!
I always did love the twilight princess princess zelda dress, she looks absolutely stunning in that dress.
there is also the Great Fairy Dresses!
Nabooru's outfit was always very fitting for the setting and attitude. Definitely an underrated costume (or rather, one people fixate on... for the wrong reasons)
