"Of course I can. The only other person present was me and I can't possibly be at fault," he said with a tiny smile. "You are not being really helpful at the moment. I hope you understand that." He shifted from foot to foot, almost willing the fabric to grow looser, even though it didn't. "Robes are much more... comfortable." They were a sort of wall that impressed people when well made, but also kept them at bay.
He turned like Remus said and watched in the mirror. It wasn't a robe, but it was much better. "It is. If Scorpius has a fit about ruining a perfectly good cut and what's in right now, and apparently it's tight and tighter according to those magazines of his- If he complains, I'm sending him to you."
He turned again and looked at Remus. "Which version do you like? And which one fits more? If I'm going to the trouble of wearing trousers, I want to fit in. I understand that it's all in my head and people aren't actually staring at my crotch the entire time. It's just- nothing I saw looked like this and I want to fit in."
