Harry has finally destroyed all of Voldemort's horcruxes and he is just a few hours away from confronting his biggest nemesis in battle. There's only one problem… Harry can't find anything to wear!
Harry indeed has closets full of different assortments of robes and yet he can't find anything suitable for battle. Naturally he thought he'd wear something black due to the nature of the event he was heading to, but he instantly changed his mind once the thought of Voldemort and probably everyone else there would be wearing that color.
'What about green' he questioned in his head. Green brings with itself a sense of venomous danger, and with Harry being parseltongue he felt it might be a reasonable assembly for the occasion. 'But Slytherin wears green' he quickly remembered. So green was out.
He would have worn the colors of Gryffindor but he knew Ron only had one set of robes, that which of course were those of Gryffindor.
White seemed plausible, being the color that symbolizes pureness, honor, and anti-evil. A flashback of the two girls Harry had taken advantage of last weekend quickly diminished any possibility of wearing white.
Yellow was a cowardly color that was often linked with urination, something Harry didn't want to remind everyone that he publicly had a problem with after consuming many butter beers.
Red is the color of blood and lots had been spilled to get to where he was. But for the life of him, none of his shoes nor his eyes matched any set of red robes he had. He often wondered why he kept purchasing such a color of robes.
He had blue robes, fantastic robes in the shade of blue but they were his favourite robes. He did not, by all means want to damage those robes in any sense of the word.
After four hours of searching his closets for a set of robes he gave up and sent a patronus to Voldemort informing him of Harry's cancellation for the evening. Voldemort quickly sent one back with his regards and asked Harry if he had tried on his grey set of robes. He also told Harry that yes; he did wear black as well as almost everyone else and had greatly regretted the choice of color.
Harry was astounded by Voldemort's suggestion of grey. Why hadn't he thought of that himself? He grabbed the closes set of grey robes and headed out to due battle against Voldemort once and for all. The challenge was a best of seven in cribbage. No magic was allowed as both sides would be closely monitored. Despite Harry's astonishing talent for cribbage he sadly lost four games to two.
After the final match when Harry had finished shaking Voldemort's hand Harry thought to himself 'at least I looked good.' The end.
