When a woman who is fat and dresses provactivley in a workplace predominatley filled with Men, she appears much better looking than she really is.

"The haley effect" allowes fat women to distory reality just enough to create the illusion of beauty
There was a secretary at my technology park who was easily a XXL girl ( aka cuddly) but always wore super high heels, nice make up and sexy corporate dresses to work. She was the only woman in a 4 floor office filled with male programmers.

Her actions, distorted reality - The guys suffered "The Hayley Effect"

Where a woman who is a 3/10 can over time distort reality ( also known as a temporal shift) to give the illusion of a 9/10 and date worthy.
