Art-rock musician St Vincent has partnered with MusicMan to create her signature STV six-string, describing it as "ergonomic, lightweight and sleek" - and adding: "There is room for a breast or two."

McGregor tells the Telegraph: "There are certain brands I can't use. They sound amazing but they have thick necks, and I have small hands. Not all girls have petite fingers, but many do, and it can make it a lot harder to play.

"Then there's the strap issue. I like to wear vest-tops, btu the fabric of the strap can cut into you. I have mine specially made in corduroy - but I really shouldn't have to.
