[WW] Why didn't Link Change his Clothes?

At the start of the game it seems pretty clear that Link isn't a huge fan of wearing the Hero of Time cosplay his grandma made for him, but he'll go along with tradition and wear it for the day. It turned out to be a little more than a day since he had to leave Outset Island, and couldn't come back for a while.

Why didn't he change his clothes when he got back? Out of Universe we know that it's the look of the hero, but in WW only the Great Deku Tree seems to care about that. It's not his only set of clothes, it's not divinely mandated that he wear it (like TP), or a uniform (like SS) or even really armor. Is there any in-game reason for WW Link to stay in his cosplay for his whole adventure?
