He had agreed to it, but he had gone in thinking
   that he had heard enough riddles in his life
   to safely sale through the challenge. Sadly,
   he was wrong.

Feeling the thief approach, Conan attempted to
   back away as quickly as he could without
   falling flat on his behind. That grin — ugh,
   that grin. He wanted so badly to swipe it
   off his cocky face, but there was very little
   he could do when blanked with his stark-
   white cape.

“Oi!” Pushing up the brim and looking up, he
   was distracted by the rustling and sudden
   remove of the cape. There was no way he
   could have been wiggled into a matching
   suit of his own size in so little ————

                                                                          ———— time!

Choking and sputtering, the boy was horrified
   to find himself wearing the exact same costume —
   the tie, the shoes, the clean suit. Even the
   monocle sat neatly above his loathsome scowl.
   And as fitting and comfortable as it was, he was
   peeve to know that he thief had gotten him into
   it without so much as a complaint from him.

“Where the hell are my clothes?!”

“Don’t worry, your stuff’s safe~ You’ll get them back later.”

Don’t mind how gleeful he is right now, just hoping the other doesn’t focus too much on the shoe change. The watch doesn’t mess with the outfit, so tantei-kun had some protection, if he needed it, and he even left the voice changer in a pocket and the belt as it was, but no electric-powered soccer balls for an irritated chibi~

…Yeah, most of his amusement came from the other’s reaction, though. Very much worth the possible harm later to see this now~

“Hmm… it’s almost like looking in a younger, irritated mirror. You should smile, tantei-kun~ You’re already dressed up, so you may as well have fun with it. It’d help with the image better, too~”
