C'est ça qui est drôle! And the one on the right is Link wearing women's clothing from Breath of the Wild. He has to pretend to be a woman to sneak into a desert town where men are prohibited. Cross-dressing is a critical part of the story, and you keep the outfit to wear in battle if you like. You can also flirt with a guy and he'll give you his boots.
I'm a completionist, so I always do everything possible in game. Strictly speaking, you only must get the sail, and you can head straight to Ganon if you're feeling mighty.
The image of low power Link charging in and beating Gannon has me remembering that streamer that made it like 90 95 hours into the game before triggering the tutorial of Breath of the Wild
I am far from mighty. If anything, I am straight up bad at combat. On my first master mode playthrough I did duck into the castle to get the shield, but afterwards went right back to do/find all the things mode.
