Public Nudity/School-Altered Shirt and Short-Shorts
You reach into your dresser and pull out a large grey t-shirt that says army in big bold letters on the front. Long story short it was originally a gift to your brother when he decided to join the army, he gifted it to you before leaving for boot camp, you tried to alter it into a tank top and only succeeded in enlarging the neckline so much it's always hanging off your shoulder. Smiling at the memories of your brother it brought back you throw it on over your head and sure enough one side immediately slips off your shoulder.
Next you reach into your shorts drawer and grab a pair of short-shorts and step into them. They're army green in color (appropriately enough) and are so small that once you pull them up over your butt and button the single brass button they're immediately consumed by your shirt. You turn to your mirror again and turn this way and that, checking out just how visible they are. When standing still you appear bottomless, but if you move the very edge of her shorts peek out from under the shirt.
With a nod of approval you move to grab some socks and shoes. In keeping with the impromptu army theme you put on some army green knee-high socks to match your shorts and a pair of brown boots. It may not be your most attractive outfit, but given it looks like you're wearing only a t-shirt (with an obvious lack of bra) you consider it a fair trade-off.
Happy with your appearance you straighten up your hair and grab your backpack before heading downstairs. Everyone else left already, leaving you on your own. You go make a bowl of cereal for a quick breakfast and as you eat you try to decide how you'll be going to school today.
