Take off her shirt and skirt and wear only the apron and her underwear/swimsuit.

(chapter originally by Phantom Pen on writing.com)

Rise smiled mischievously as she quickly tossed off her apron and went about removing her shirt and skirt. Practiced at quickly changing from her idol work, Rise was standing in front of her mirror in just her underwear in no time. The starlet couldn't deny that she cut an impressive figure standing there in her lacy orange undergarments. That definitely fulfilled the Risette aspect of her look.

Picking the apron back up, Rise quickly tied it around herself once more. Appraising herself in the mirror, Rise was satisfied with what she saw. From the front, everything seemed innocent enough. At most, someone would assume she was wearing shorts and a tank top, but a view of her sides or from behind would disprove that theory in an instant. It was naughty, it was risque, and Rise was loving it!

"And just like that, Rise and Risette are fused into one!" Rise said to herself happily as she skipped out of her room and back to the store front.

A thrill went up Rise's spine as she took her place at the register. The shop was still dead, with no signs of changing, but that didn't lessen the excitement from this little stunt of hers. Here she was, plain old Rise in the front, and scandalous starlet Risette everywhere else! This test of blending her styles was quickly proving itself to be a rousing success!

At least it was, until things changed...
