"Here", said Alexis, "Try on this pair of jeans. "My aunt that lives out West bought them for me, but they're way too big. No matter how many times we tell her the right size, she always gets it wrong."
Alexis went to the bathroom while Mark changed into the jeans. They were a tight fit, but he managed to get into them. When Alexis came back, she was wearing the clothes Mark had brought. She eyed him up and down, then handed him something, and said, "Take off your shirt."
"OK", said Mark. "What is this?"
"It's a corset", she said. "It'll help give you a more girlish figure. I borrowed it from my Mom. She's kind of amused by this whole idea."
Alexis helped Mark put the corset on.
"It's hard to breathe in this thing", said Mark.
"Sure it is", said Alexis,"That's why Victorian women were always fainting. their corsets cut their air off."
She helped Mark put one of her loosest sweatshirts on.
"Hmm", she said. "Needs a little work. How do you think Ilook? Am I a convincing boy?"
"Not really", said Mark.
"Well, I tell you what", said Alexis, "Let's not do this half-heartedly. Let's do a little shopping, We've got plenty of time.
The two of them changed into their regular clothes, and went to the mall. An hour later, they returned to Alexis' home. Alexis took some of the purchases and left the room. She returned about half an hour later, in full costume. Mark was impressed. He could still tell it was her, but she looked a lot more "boyish".
"I had my Mom help me bind my breasts with some bandages", she explained. "You'll suffer with the corset, I'll suffer with this."
Her hair was gathered up under a baseball cap.
"I thought about dyeing it, she explained, "But my hair color isn't that different than yours. Mom did a little make-up on me, too."
She had what looked a bit like five-o'-clock shadow, so long as you didn't look at it too closely.
"Are you taller?", asked Mark.
"Lifts in my shoes", explained Alexis. "Anyway, let's get to work on you."
She had him put the jeans back on, along with some frilly blue socks, and a cheap pair of mary-janes they'd bought.
"At least with those jeans on", she said, "you won't have to shave your legs."
Next he put the corset back on, and a bra they'd procured. Alexis stuffed it with tissue paper until she was satisfied. Over this, he put on a sky-blue blouse they'd found.
"This is just the sort of thing that I'd wear, it's just in your size."
Alexis put some fake fingernails on him, and then carefully polished them in her favorite color. She's had him shave earlier, so she set about making him up, and putting false eyelashes on him. Then she put a wig they'd bought on him, and fussed with it a bit She put a multi-colored silk scarf on him to cover up his Adam's apple, and topped it off with the bomber jacket that she'd "liberated" from her brother, which she wore everywhere.
"Not a bad job, if I say so myself", she said.
Mark looked at himself in the mirror. Alexis had done a good job. No one would mistake him for her, but if she'd had a cross-dressing big brother, he might have looked like a bit like Mark did right now. Alexis, on the other hand. still managed to look as cute as a button, even dressed as Mark.
They took a deep breath, and showed themselves to Alexis' mom, who laughed and took a picture to send to Mark's mom. She and Alexis gave Mark a few pointer on how to move like a girl, and he and Alexis practiced doing each other's voices.
Finally, it was time to go to the party, which was being thrown by their friend Jamie. Alexis' mom drove them to Jamie's house.
"OK, kids", she said. "I'll be back to pick you up around. Be good, and have fun."
Mark and Alexis left the car, and walked up to the front door...
