Something that requires a longer detour

As Mary and Serena led Julie down the hall, an idea popped into Mary's head.

"You know, with how tight that shirt is, it might make it easy for other students, or even a teacher, to tell you and Nina are the same person..." Mary mused.

"You think so?" Julie asked, a bit nervous.

"Oh, definitely. I think a larger shirt would conceal your secrets better." Serena added, winking at Mary, who smiled back.

"Yeah. Stay here with Serena. I'll just head back to the locker room and get a shirt I know will be big enough. It might even be as long as your shorts!" Mary said, quickly leaving the others in the hallway.

Julie heard Mary scamper away and turned to Serena. As she did, the baggy shorts fell to her ankles. Serena was shocked at first, but played it cool, not wanting to alert Julie, who seemed none the wiser.

"You know, you should give me your shirt, so you can put on the new one as soon as Mary gets back." Serena suggested.

"But...what if someone comes? They'll see I'm topless. As in ME, Julie. I can't imagine what would happen if anyone saw me naked, and realized I look the same as Nina." Julie replied.

"True. Ok, just stand there and wait." Serena replied, hoping Mary would return soon.

Meanwhile, Mary had entered the locker room and entered the coach's office where she found what she was looking for. A devilish grin appeared as she left and went to join Julie and Serena.

"Hey, she's back, and it looks like she has the shirt. You better take off yours now." Serena smiled.

"Um...ok." Julie agreed and pulled her shirt over her head, standing fully naked in the hallway.

"I got the shirt. Here, lift your arms up." Mary said.

Serena smiled as she held Julie's shirt in one hand and her phone in the other. As soon as Julie's hands were up, she snapped a photo without her noticing. Mary pulled the shirt over the naked girl while Serena bent down to pull the shorts back up.

"There! Fully covered and large enough to conceal the fact your not wearing underwear. And making sure your true figure isn't noticeable." Mary said.

Serena had to stifle a giggle as she saw what was written on the front of the shirt. It was meant to be worn as a swimsuit cover for the girl's swim team, but the slogan proved to be too suggestive. The coach kept them as rags, but no one knew the story besides the coach, the swim team, and the principal. Mary and Serena happened to hear from one of the cheerleaders who is on the swim team about it. But neither had read what it actually said. Now they have, they were amused by how perfect it was for Julie.

The cover definitely hung loose and came down to mid-thigh, which left a good amoutof her shorts exposed. However, instead of an elastic band to hold it up, it had 2 shoulder straps that tied, which would be very easy for either otlf them to untie during the day...

Compounding this was the misleading slogan on the front, which read "Slippery When Wet", but was printed a bit low, to suggest it meant the pelvic region.

The girls then escorted Julie to class.
