Molly giggled, glad Madam Malkin wasn't around to hear that. She liked being known as the best and anyone even joking that her associate might be the pick of the crop would have put her in a mood for the rest of the shift! "It's, like, always freezing at The Ministry, you know better," she lightly admonished her friend. She nodded though, with a smile, and said "Right this way, darling," and ushered Cassandra into the main shop.
"What are you looking for in particular? You know we have the usual Ministry robes available, though I don't know if you're required to wear those in Mysteries?" She never asked Cassandra about her work - it was just the case of being friends with an Unspeakable - but she figured asking about the dress code was allowed.
