"Okay, okay..." you chant under your breath, struggling not to panic. "My feet are just tucked into the tailfin, nothing weird. I just need to get this costume off and everything will be fine." You're gasping slightly, as if the air is too thin to breathe, but you tell yourself you're just hyperventilating and to calm down.
A bit of blue hair falls into your line of sight and you start to panic, wanting every piece of this outfit off as quickly as possible. Sliding your fingers around your hairline, you become frustrated that you seem unable to find the edge. Giving up, you grasp a clump of hair at the crown of your head and give a hard PULL... only to let out a *Yelp!* at the sharp pain this causes.
"What the hell?" you think, twisting your head this way and that in the mirror, trying once more to find the edge of the wig cap. "Is the cap hooked in someway to prevent it sliding off accidentally?" Tugging on strands of blue hair only serves to panic you further, as each strand seems firmly attached to your scalp. You can't find a wisp of your brown hair sticking out anywhere! Brushing the bangs aside, you *Gasp* as you realize that your eyebrows have somehow changed color and shape, both now a thicker, bushier dark blue! Tracing your hands over them, you notice your nose - it Definitely didn't have that bony arch when you came in here! Leaning back, you take in your face in it's entirety: Wide greenish eyes beneath thick, blue eyebrows... are your cheekbones a little broader? Your jaw is definitely wider and your chin now seems to have a very faint cleft to it! You look like yourself, slightly, but more like if you were born a boy!
Taking your gaze lower, you realize that your breasts have all but disappeared. Your nipples are smaller, resting atop firm pectorals on a chest that is definitely broader than before. Your shoulders have broadened too, and the muscles! You suddenly look like you've been lifting weights, daily, for years!
"What. The Fuck." your firm jaw drops open, physically relaying your complete lack of comprehension of what you're seeing reflected in the mirror. Your fight-or-flight response kicks in and you unconsciously try to stand, forgetting the restrictive "costume" you have on. You jolt halfway up before abruptly toppling sideways, just barely catching yourself with your muscular arms before you face-plant on the changing room floor.
