Does Beatrice wear a costume to work?

Yes, under her modified work attire

By the time she left the cafe, she still had about 4 hours until she need to be at work. She decided to pick up a few items that would make her night a bit easier for her.

She picked up a pencil skirt that was two inches shorter than the one she was wearing, that had a slit in the back that ran up to her butt when she bent over. At the same store, she found a blazer and button-up shirt that were a size too small. She then went to the sex supply store nearby and picked up a butt plug and some lube, as she wanted people to know she was open for business.

After much debate with herself, went home to get ready. She took a shower and decided to change one thing about her appearance with the book that wouldn’t be seen by anyone unless she was bottomless. Satisfied, she got re-dressed for the night. Her breasts were now covered by just the smaller shirt and blazer that barely closed, while her pussy’s only cover was the shorter skirt that was tight around her hips. She completed the look with her shoes.

She spun around in the mirror, pleased with what she saw. Excited for the evening ahead, she grabbed her purse and drove to work.
