Regulus felt very ambivalent about this trip. While he wasn't a fan of Muggle culture, it was hard to keep a separation when there wasn't a real wizarding culture. It was also nice to go back to London and see people. Twenty-five people were just too few to never meet anyone else.
The other problem was the clothes. Regulus wore robes. He liked them, loved the way they felt, enjoyed the way they moved when he walked. He never wore trousers, not even wizard ones. He remembered the Muggle trousers of the 70s. They were much tighter than the wizarding counterpart, but after time with Scorpius, he realized that today's trousers were even tighter. They were fitted from top to bottom. The jackets were single breast and covered a lot less than those three piece suits that business men wore in the city.
Looking down to the blue suit that Scorpius had transfigured, he went to Remus who didn't seem interested in looking at clothes. "What do you think? Scorpius says that it's a bit too formal and vetoed the waistcoat. I feel indecent."
