I've written this some time ago and only published it on the Winx Club Amino as this was a request by the user JenessaNL who challenged me with Kiko and J (It was a special moment to dress up for) from a prompt list I had there

Also, this ignores everything after the first movie

"Are you sure about this, Stella?" Sky asked, hesitantly. "Oh, I am so sure of this, you look much better in white" There was no one better than Stella to coordinate Sky's suit. "But I heard Bloom will wear white as well since it's an earth tradition" he voiced his concerns, but Stella waved them away. "You will both look stunning and matching, don't you trust me?" Sky's shoulders sagged and he looked like he wanted to look for another excuse.

Anything Stella might have said, was interrupted, when Kiko jumped into Sky's arms. "Hey there little buddy" Sky greeted him and Stella pursed her lips. "Out with it, what is truly bothering you about wearing white? I thought it was Eraklyon's tradition for the groom to wear white" Sky's eyes widened, then he sighed. "I feel like, I don't know, when I was under Valtor's influence and Diaspro made the wedding preparations, I wore white for the dressing and that was when you freed me. I don't want anyone to remember that, least of all Bloom. I hurt her enough, so maybe I should follow her tradition"

Kiko patted Sky's hand and Stella looked thoughtful. "I think what matters to Bloom, is that it is you waiting for her, not Diaspro. She knows you only love her. And you are not from earth, but Eraklyon. Besides, even if they do remember, you're not marrying the wrong person, you are wearing white for Bloom this time." Sky's lips quirked up. "Thanks, Stella."

Kiko, looking between them, looked at Sky's suit. "What do you think about my wedding suit?" Sky asked the bunny, with Kiko's answer hopping of. "So, you don't like me in white? Should I wear black after all?" Sky questioned Kiko again but Stella's glare made him shudder. "No, you are the King of Eraklyon, you will have to respect your traditions. Besides, you don't look as good in black as you do in white. Black is so not your colour"

Kiko returned with a scrap of black cloth, holding it to himself. "Black fits Kiko much better" Kiko nodded enthusiastic at Stella's statement. Then she lit up. "Idea" she shouted, surprising Sky. "Should I ask?" He did not need to ask, Stella pointed at the cloth, magic swirling around it, forming a tiny suit. Kiko did not waste any time, stretching his limbs into his own suit. "Oh, this is so adorable" Stella cooed.

"What a handsome man, stealing my show?" Sky grinned at Kiko. The two posed for Stella until she was satisfied, nodding to herself. "The two of you will be the best dressed for the wedding" And when the wedding day finally came around, Bloom swooned over her bunny wearing a wedding suit.
