In OoT Link starts with the heros clothes like in all the other toi get the heros clothes but how come all the kokores have the same clothes?

It's argued that Ocarina of Time marks the very beginning of the Legend of Zelda. The subsequent hero clothes are worn in honor of the original hero, ou the Link represented in this game, and he wore it because it was the garb of the Kokiri.

This theory is contested, however, especially par several who believe that Minish casquette, cap is the original beginning, as it can explain why he wears the hat, but I personally believe it's OoT. That's the best answer I can offer you.

The chronology of Zelda is highly contested, and toi can read plus about it link.

I think according to OOT story, the Kokiris wear green clothes because they're from the forest, and they thought Link was too. After he becomes a hero, but he remained with that clothes.
According to the other stories, he wears that clothes because was the clothes of the hero that would save Hyrule.

They are all the same, Like 7 years later they're just the same so why they need different clothes? :D

toi know i have no idea.i gotta play it.i think its pretty cool.

Yeah like cinder a dit all the liens are different, except for ocarina of time and majora's mask. Though i do agree that Oot should be considered the earliest on the time line. Plus as added proof of the whole different liens idea, the mastersword is in a completely in different places, and in some they don't even exist.

?
mabey they like it.

they were that to represent the hero of time (Link)......skyward sword is actually the first game in the timeline cause no one inhabited hyrule yet
