A Very Lilac Lunch

Severus Snape has run the gauntlet of Hogwarts, survived the initiation into the Death Eaters, and is now facing his hardest mission of all...enduring Lucius Malfoy's wedding. But before he has to walk down the aisle with Bellatrix at his side to watch Lucius and Narcissa pledge their lives to one another, he has to get his robes, and ugh, is that LILAC?
