It happens when Sol is getting his clothes fitted for the wedding.
The colors he will wear are midnight with gold and ruby jewels. In contrast, Nox will be donned in ivory wearing silver with sapphire gems. They are night and day, dark and light. It's a fitting theme for the two of them and as they are Supreme Gods, there are no specific rituals that they have to adhere to. In short, they can pretty much just do whatever they want.
It's Silynna that fits them, taking their measurements and pinning long pieces of fabrics to see how they would look.
Sol tolerates the process only for Nox's sake.
It's not that he isn't looking forward to their wedding, he is. But the ceremony doesn't appeal to him half as much as it does to Nox. But seeing his beloved so excited about the little details is extremely cute, though at times tiring.
