Shenanigans

Look, the potion is going to wear off in an hour. After that, I'm going to go back to being your dumpy old roommate Phil.  So you don't have long to decide. Do you want to go crazy with your dream girl, or do you want to dither until the choice is made for you? Me, I vote for shenanigans...

Model

"Doctor Gimmelstup, I can understand how the bodysuit can reshape Brian's body into any form you desire, but how did it manage to change his hair and face as well?"

"You see, Benton, the suit is only the outer and most visible layer of a whole system of morphic nanite technology.  Literally, there is no aspect of Brian that we cannot program.  For instance, I have made a few mental modifications to help my graduate student to get used to his new body. Look at how he is checking you out, now."

The Changerains

The Changerains caused havoc when they first started turning people into sexy young women. I was one of the few people who secretly rejoiced.  Still, the showers were rare, and I had to wait for months for a changestorm to strike my area. When it hit, I got appropriately dressed and stepped out into the downpour, waiting for nature to give me the body I always wanted.
