Had sudden inspiration for this one. Decided to try something slightly different. Kind of short-story style from Conan's perspective.
It all started when Conan's clothes got ruined on a case. With everything else already in the wash he was forced to wear some of Ran's less girly clothes from when she was his age while she washed something for him. Meanwhile, not wanting anyone to see him, Conan opted to wait in Ran's bedroom for his clothes to dry. Unfortunately Sonoko, having heard about the case, picked that exact moment to burst in the door desperate to make sure that her friend was alright.
Sonoko : "RAN!"
Conan cringed as Sonoko thundered into the bedroom begging any gods that might exist not to let her notice him. She did. The Suzuki heiress took one look at Conan and burst out laughing. Then, grinning evilly, she pulled out her camera-phone.
(She wouldn't dare... would she?) he thought.
Sonoko : "Say cheese, brat!"
*CLICK*
Of course she would. Conan sighed in resignation as Sonoko snapped away with her phone cackling maniacally with every shot she took. He prayed she wouldn't show the pictures to anyone, but he knew it was a fool's hope. Shortly everyone in Tokyo would probably have a picture of him in a pink dress. One thing he did know for sure. Hattori was never going to let him live this down.
