Sir Mick Jagger "can’t function" in jeans.
The Rolling Stones frontman can’t understand how his bandmates used to feel comfortable under hot stage lights in denim trousers, and also rejected leather garments because he found both materials too restrictive.
He said: "Keith [Richards] and everyone would always wear jeans.
"I can’t imagine how you could function in jeans. There’s no give in them.
"Now, people still manage to do a lot of amazing stuff wearing jeans. But for me, it wasn’t a great feel – too think, no give, and not so great when you got hot either.
"I never used to wear leather either. Like, Jim Morrison would wear leather pants. How do you even do that?"
For the 72-year-old rocker, comfort and practicality is essential on stage.
He told MOJO magazine: "Comfortable is a big thing if you’re on stage.
"I used to wear these moccasin shoes – bought them somewhere in California.
"They were very ‘the thing’, but they’re not very good to dance in – I can’t imagine how I thought I was gonna dance in moccasins."
