You decide to start modest, but not too modest. You could make the small changes later.
You take stock in the mirror at your appearance as a man. 6 feet tall, fairly attractive with fair amount of muscle, brown hair, and blue eyes. It was not like you disliked being a man or being masculine, you merely wanted to test the flashlight and take the opportunity to experience what life as the "fairer sex" is like. After taking stock of your current appearance, you were ready to change.
You set the flashlight to a setting in between medium and bright-pink and aim it at your feet. They immediately get smaller and more delicate, and your tennis shoes become open-toed sandals. Your toenails are painted a simple red color.
You then bring the light up your legs, avoiding your junk for the time being. Your legs become slimmer and you watch your perspective drop a bit as you lose a few inches in height. Your jeans become tighter until they become skinny jeans. You notice that your legs are also cleanly shaven. Your hips widen and your butt swells up and becomes more rounded.
You then move the light to your torso. You feel some of the muscle dissolve away and you get even shorter in height. All the hair on your torso disappears and you feel your chest swell up and expand until you have full c-cup breasts, with a bra to match. Your t-shirt becomes a red v-neck that reveals a small amount of cleavage. You then shine the light from your shoulders down to your arms, which become slimmer as they lose muscle and appear to be shaved and your shoulders narrow. Your hands grow smaller and more delicate as well.
You first bring the light up to your neck just below your chin and you watch your Adam's apple disappear. You suspect you now have a feminine voice. You then close your eyes and sweep the light up to your head. When you open your eyes, you notice that you have a fairly attractive face (not drop dead gorgeous, but you would definitely date yourself), pierced ears with small pearl earrings, and your straight hair falls down to the middle of your back. You aren't wearing any noticeable make-up, but you somehow know that you have some at home.
All that's left is your junk, you shine the light at your currently hard penis, which immediately starts to shrink and your balls become ovaries. You pull your pants down to examine your new vagina, and notice that your boxers have changed to plain white panties. Your vagina looks cleanly shaven, you touch the clit and immediately feel a sense of arousal. You pull your pants back up, put the flashlight in your pocket, and examine your work. You look like a completely normal, if not attractive girl: not merely plain, but not super gorgeous, and about five inches shorter than you were before.
