In the dressing room you begin to look at the dress the woman gave you and you dicover to your shock it is a dance hall girl's outfit. You can't wear this? It's way too skimpy and shows off parts of your body that you really don't have.
You call out to the woman. "I can't possibly wear this. Do you have something else?"
"Go on and try it silly boy."
"That's just it, I'm a boy. A flat chested boy, this thing is made for a busty girl with nothing to hide."
"Just try it on and in a few moments you will see just how well you will look in it."
You silently nod as you begin to put the outfit on. You start to feel all tingly when you face the mirror, and you gasp at the strange site before your eyes. Parts of your body are shrinking while other parts grow and swell in size. Your chest in particular becomes very soft, tender, and need I say well endowed. You touch them squeezing the nipples and cry outloud in a pleasurable moan.
"So, I take it that you like your new costume my dear?"
You turn around to see your beautiful round derriere and smile with your luscious red ruby lips. "OH YES! Thank you so very much! I never knew being a girl could be this much fun."
You walk out to meet the woman who gave you the outfit.
"I know, that’s what all of the boys say at first. Now, we need you to go on stage tonight to perform your big number."
You frown. "What number?"
The woman giggles. "Why The Can-Can of course you silly little girl."
