You grab a pair of sweatpants, with a cotton jacket and a tank-top to wear under it and get to the changing room.
As you remove your old, constricting clothes, you feel like you can finally exhale a breath you have been holding ever since you first bit down into that absurdly delicious burger. Looking at your naked body in the mirror, you can hardly recognize yourself between the weight you've gained, and your ridiculous haircut.
With a heavy sigh you pull the sweatpants up, and they fit like a glove! While the fabric is almost skin-tight, you it feels far more comfortable than your old boot-cut jeans. You toss the tank-top on, which you admit you only got so you don't feel as naked while wearing the jacket, as you can see that the main part of the garment, while keeping your chub under control, only goes up an inch past your nipples; as a pair of straps that go over your shoulders hold it up. Then you slip your arms into the jacket, and zip it up to the top.
Now you look like you look like one of those joggers you sometimes saw in the park, they might not have been in shape, but they at least looked like they were trying to make a difference. As you pick up your old clothes and turn to leave the changing room, you get an eye-full of how your new sweatpants frames your chubby tush, but you push the thought out of your head, since now you feel like you still need to find some kicks to replace your old ones. You find some awesome looking pumps, that even match your sweatpants and jacket, and look for a store assistant who could help ring you up.
With a strangely building sense of pride building within, you strut your way out of the department store with newfound energy to confront that barber and get your hair did the right way this time.
