But even still, as much as you like this costume, you can't be a girl in the boy's bathroom. On the other hand, the idea of it is starting to feel slightly more appealing, and you're not sure why... You feel like the subconscious part of your brain is already trying to construct excuses for why you could just walk out of the boys' bathroom like this, as a small girl in a fairy costume. None of the excuses you've thought of so far are any good, and you're almost worried that you might actually come up with an excuse that seems acceptable if you think about it long enough. Probably bad news all around.
So, you decide that the only natural thing for you to do at this point would to go back into the bathroom stall and change out of the costume. Walking away from the sinks and mirrors, you almost skip--so light on your feet!--on your way back to the open stall door. Your old clothes are still in there on the floor; a button-up shirt, a pair of cargo shorts, socks and shoes...but somehow they look more worn out and faded than they did just a few minutes ago.
You close the door, and are surprised when the normally cramped space seems so much larger with this different body. You could stretch out as far as you wanted in here! You're certain that if you sat on the toilet, your little feet would dangle a few inches above the floor. Still, it's just a bathroom stall, and you're not going to stay here. You look down at your clothes, and then at yourself, marveling that both pairs of clothes fit you. Your head feels a little dizzy trying to think about it, but the line of your boxer shorts--which don't feel any different at all--is clearly visible beneath the tights.
