Jack Grealish rose to footballing stardom in 2019 when he captained Aston Villa back to the Premier League.
Since then, he has established an instantly recognisable look on the pitch.
The headband, long-sleeved undershirt and very low socks are staples of Grealish's on-pitch appearance, but it all started back when he was a teenager.

Jack Grealish calves: Why he wears his socks so low
In an interview with GQ in 2021, the Manchester City man explained the roots of his now iconic sock style.
"It began during one season when I was 15 or 16 and the socks in training kept shrinking," Grealish said.
"I had to wear them underneath my calves and that season I ended up playing really well. So I ended up keeping them like that and to this day I’ve still got them."
If you're watching England play and think Grealish's shin pads look comically small, it's because they are.
"My shin pads are kids size, seven to eight, so that’s why they’re so small," he explained.
This isn't the first example of superstition from the Birmingham-born midfielder.
In Aston Villa's run to promotion in the 2018/19 season, Grealish sported a pair of severely worn-down football boots.
Jack Grealish calves calendar 2023
One thing about wearing short socks is that it tends to leave your calf muscles on show. For Grealish, this has generated a whole new fanbase.
Kevin Beresford, a grandfather of two, created a 2022 calendar celebrating Grealish's impressive lower legs. It was so popular that he made a "sequel", which went on sale ahead of the Qatar World Cup last November.
"It was my best-selling calendar last year and that's what pushed me to do a sequel," he said, as per the Manchester Evening News. "The pictures are better this year, his calves have got better and bigger and they look more beautiful.
"I've said before Grealish has the calves of a Greek god and now they even look less hairy. Whether he shaves them I don't know but I think they're luscious this year.
"His calves have become iconic — he always wears his socks rolled down with dinky shin pads to show off his legs every match."
An Aston Villa fan, Mr Beresford said he received orders for the calendar, which was priced at £12.50 ($14.90) from all over the United Kingdom.
