Old fashioned to sexy

During the last Youth Day, Lucy told to Celest, her grandma, that, even if when she was young, she still looked like an elder. Indeed, Celest didn't know how youngsters dress nowadays. And with her clothes choice and her old fashioned hairstyle, anyone could see she was just an old woman on the inside.
Then, Celest decided to ask her granddaughter if, the next time, she could help her. The deal was : they will go into a nightclub and if nobody could assure she was a rejuvenated one, she'll help Lucy pay her car. Motivated like never, Lucy prepared herself for the next Youth Day.
When it began, she welcomed ecstatic her young grandma. She then took her to her wardrobe where she curled Celest, before showing her what clothes she choosed. Lucy's theme for her grandma was "sexy as hell".
That's why, when they went together to the club, nobody guessed they were in front of two girls with 60 years of difference. Men were too focused on this beautiful and confident woman called Celest.
And the next day, as Celest finally came back to Lucy's house after a wild night, Lucy could claim her price.
