Why would anyone get stocking seams tattooed on their legs?

I saw a girl in the mall with them. She was wearing cut off shorts and flip-flops so I could see that she even had the keyhole or finishing loop at the top tattooed on. She even had a tattoo of the heel treatment! Why not just wear seamed stockings everyday if you wanted to, like I do. The sad part is, with the tattoo, she can't actually wear seamed stockings because no way could she get the seams to match up with the tattooed seams. Odd.
