You quickly remove your bra and use a hair tie to pull your shoulder-length hair into a small bun at the nape of your neck. Picking up the blue wig, you settle it on your head and begin tucking your own hair under the edges of the cap, arranging the synthetic layers to look more natural. It's shorter than you thought when you picked it up, more of a boyish cut with long bangs that you part slightly over your forehead. Luckily you can't see any of your own brown hair underneath. It's amazing how much a change in hairstyle and color can change your overall appearance!
Picking up the tail from where you'd draped it over the changing room stool, you stand on your left foot to slide the first leg in. The wetsuit material doesn't make this easy though, catching against your flesh like rubber until your right foot finally pops out the bottom. Standing with one leg in and the other out, you realize it might be easier to sit on the stool as you guide your other leg in. In just your panties, you sit on the padded cushion and begin to slide your left foot down along your right leg. It's really tight, and as your foot finally reaches the hole you wonder how you're going to walk with your legs squished together like this. You wiggle your feet, but there's not an inch of give from your thighs to just above your ankles. Using one hand to press up and off the stool and the other to balance against the wall, you rise to stand and pull the tail the rest of the way up and over your hips.
"Shit." you think. "I hope I don't need to use the toilet at the party! This thing is almost impossible to get into, I can only imagine how difficult it'll be to get off! Gonna have to limit my drinking a bit..."
Glancing around, you can't seem to find the seashell bra. You could have sworn it was tangled on the hanger when you hung it on the back of the stall door, but now it's nowhere in sight. Maybe it fell off and bounced under the door? You're not about to try to crouch down in this tight tail though; with your luck, the thing will split and be destroyed, no matter how thick the material feels!
Waddling in place, you turn to inspect your look in the mirror. The tailfins laying in front of your feet are definitely awkward - you're going to have to kick them ahead of you with each step so as not to trip. That's if you can actually walk at all in this skirt! Gazing into the mirror, you're very pleased with the overall look. The thick, weighty latex of this costume gives it a much more realistic look than some flimsy material with sequins would. You can probably rummage around at home for a bikini top if you can't find the seashell bra, but you're not really worried about it at the moment. The wig really tops the costume off, the color complementing the scales and making you almost unrecognizable to yourself. The cut seemed to emphasize your jawline, making it seem a little sharper and stronger. The way the long bangs framed your brows made them stand out a bit more as well. Makeup would probably soften the look; maybe the store has some shimmery stuff that you can use to paint a few matching scales on your arms and hands.
