She decides to put on an old school-type swimsuit.

"Really, guys, can you please help me find my swimsuit, the contest is only a few minutes away, and i don't want to deal with whatever miss kashiwagi's punishments are", Naoto said as she pleaded her friends to find her swimsuit.

"We're trying, but i can't find it anywhere...", replied Chie as she searched the bathroom with the girls.

"Maybe someone stole it ?", commented Rise as she thought about it.

"Yeah, it could be, but in that case, do any of you have an spare swimsuit you can lend ?", Naoto asked.

"Sorry, i had one, but i didn't brought it today", Chie responded, with Rise and Yukiko nodding too.

"Hey, don't worry, here!, i think i found something for you!", exclamed Yukiko as she threw something to Naoto's stall.

_"An school swimsuit ?", said Naoto as she inspected what Yukiko gave her.

"Yeah, i found it laying in the cabinet, it's a bit old and small, but i think it will serve you well", Explained Yukiko with an smile.

_"Well whatever, it's fine, thanks i guess", replied Naoto, for she knew that this was her option, upon which, she began to put it on.

A few minutes later, just before the announcer called them to the podium again, Naoto emerged from her stall, wearing nothing but the swimsuit. As Yukiko said earlier, the swimsuit was visibly rather old, and had many discolored parts. Not to mention that it was of the wrong size for Naoto, making it feel even tight than what she expected to be.

"Well, it's not like i wanted to win the contest anyways", Simply said Naoto as she composed herself, "Let's just deal with the swimsuit part as fast as possible and be done with it", she said.

"Yeah, let's just go", said Chie and the others, upon which, them and Naoto began to walk towards the podium to deal with the swimsuit competition. With Naoto worrying that the swimsuit left little to the imagination.
