Why not go for the bright option, you reason to yourself. The flashlight can reverse things just as quickly if it doesn't work out.
You decide to start with your feet to be on the safe side though. You bend over, pointing the flashlight at your feet, and flip the light to the bright pink setting. As the light washes over your feet, your tennis shoes seem to melt away into nothing. Your feet slim down and your toenails are suddenly painted a bright red. You start to lose your balance and have to sit on the bench in the fitting room, then you see why you lost your balance. Your shoes have become silvery-colored high heels which are really nothing more than a sole, a four-inch heel, and some thin straps to hold them to your feet. You take a moment to admire your new feet and wiggle your toes. You notice that the polish on your toes also seems to have glitter mixed in with it.
You aim the flashlight at your ankles and watch as your jeans begin to recede up your legs until they are out of the pink light. The area of your legs under the light is now free of hair and significantly slimmer. You are intrigued by the action of your jeans and continue to raise the pink light higher up your legs, exposing more and more of your feminized legs. When you reach your mid-thigh, your jeans finally metamorphose into a denim mini-skirt. You hesitate for a moment wondering whether to continue up your body anymore. The experience has excited you, and you can see a growing lump in your crotch. You take a breath, close your eyes, and bathe your crotch and hips in the bright pink light. You feel your penis deflate and then a general, warm sensation engulfs your groin. You can feel that your underwear has also undergone a drastic change. You open your eyes and stand up on your high heels, feeling more balanced than the first time. You shine the flashlight on your butt to make sure it was affected as well. It feels as if your butt inflated and perked up a bit.
You examine yourself in the mirror, turning off the flashlight for the moment. Everything from your hips down is completely female, not to mention very sexy. Your denim mini-skirt shortened a little more with that last flash of pink light; it is now cut just barely underneath your groin area. You turn to the side to get a view of your full, round ass. You reach under your skirt and feel the silky smooth flesh of your rear, which makes your vagina tingle. You lift up the skirt all the way and observe that your underwear has morphed into a thong that is just able to cover up your feminine slit. You peel back the thong slightly and confirm that your pussy is cleanly shaven like the rest of your lower body.
Your arousal is starting to grow, so you decide to finish the transition so you can have fun in a complete body. You turn the flashlight back on and shine it on your waist. Like your jeans, your shirt begins to recede as you watch your belly flatten and slim. You move the beam up to your chest, and feel the same feeling as before as your breasts begin to grow and your undershirt becomes a bra. You hold the flashlight in place, a little curious to see just how large your breasts can get. Then, as your breasts grow to DD cup, you suddenly lose the feeling of wearing a bra. Now the only thing covering your breasts is your shrunken shirt. You take the light off your chest to see the result. The skimpy top you are now wearing barely contains your DD breasts, but shows plenty of your cleavage and your erect nipples poking through the fabric. You shine the pink light over your arms to finish the effect on your upper torso. Your hands slim down, and your fingernails grow out and are painted with the same glittery, red paint as your toes.
You take a final deep breath and point the flashlight at your face. The bright, pink light blinds you for a second, but you feel like a wave of warm water washed over your head. You open your eyes and look in the mirror at your new face. You're a true vision of beauty. You have full, pouty lips covered in red lipstick. The rest of your face is also covered in make-up; rouge on your cheeks, mascara on your long eyelashes, penciled eyebrows, and a perfectly powdered nose. You have wavy, blonde hair that trails down to mid-back, and even your ears are now sporting tasteful studs.
Every man is going to stop and look at you.
