Draco had noted the change of clothing on Jake. He appreciated the effort, but honestly he preferred seeing him in his usual clothing. Draco was wearing his usual formal clothing...and it's darker tones

"Sorry for the last minute planning," Draco apologized. Leading him inside, Draco then in turned introduced Jake to Remus, Tonks, and then Teddy. He tried to keep things smooth. He did his best to try and keep things going, but hosting anything was not a strong trait of his. It had always been his mother's. He was thankful for Jake's calm demeanor and found that it helped his own nervousness.
