For decades Olympians have inked Olympic Rings.
In some countries, athletes get tattoos when they first qualify for National Team.
Most conspicuous are the facial temporary tattoos worn by NCAA gymnasts.

Entrepreneurs take note, clubs do not yet have their own temporary tattoos. The girls I’ve seen use make-up and glitter — perhaps even felt marker — to draw their own.
This could be a good business opportunity.
