I noticed a problem with my new uniform

All the girls were ripping the plastic coverings off the new uniforms and stripping off their old uniforms. Mrs. Johnson was coming around with a big plastic bag and made everyone put all of the old uniforms in the bag. Mrs. Johnson said that the school was going to give our old uniforms to another school in a poorer district, so we were to put in the whole old uniform: Skirt, sweater, socks, bra and panties. All the girls did that and hurriedly started putting on the new uniforms. I looked around for a moment and found my thoughts turning briefly to all of the naked and nearly-naked girls' bodies. I felt a bit awkward and then Sally came by, already dressed in her new uniform, which looked great, and said, "Mrs. Johnson said to hurry up and get dressed," and she smiled at me as she went back out to the gym.

I looked at my friend, Amy, and she said, "Hurry up, Julia!" And ran out of the locker room. I picked up my uniform and it fell out of a hole in the plastic onto the bench. I picked it up and was shocked. All that was there was the skirt, the sweater and the socks, with no bra or panties! I looked around in a panic, but all the other girls were already finished and I was the last one in the locker room.

Mrs. Johnson came out of her office and was going into the gym and I yelled, "Mrs. Johnson!" But before I could tell her about the problem, she looked at me and said "Hurry up, Julia, you're not even dressed yet! The pep rally is about to start!"

Well, I couldn't just sit naked in the locker room, so I put on my new skirt and sweater, but when I stood up, I cursed. "Stupid Sally must have given me the wrong size!" The skirt was at least two sizes too big for me and so kept trying to fall off. The sweater was way too small, and one of the seams started to tear when I stood up.

I looked in the mirror, trying to decide what to do. The sweater was so tight, that it made my breasts look really big, and without a bra, you could see my nipples poking through. The skirt was too big, but if I didn't move too much, and kept my legs pretty far apart, at least it wouldn't fall off. I turned around and looked over my shoulder for a back view. I could see where the seam on the side of the sweater was tearing. And since the new sweater was short and my skirt was riding low, I could almost see the top of my ass crack!

I didn't know what to do. I thought I couldn't go out to the pep rally dressed like that, without any bra or panties and everything, and I thought maybe I should just wait in the locker room until after the rally, so I could talk to Mrs. Johnson and get a better-fitting uniform. I was trying to decide when I heard the door from the locker room to the school hallway open and
