Here's a skirt that looks really smart - it's made with 80 smartphones!
The screens are all linked to a computer which synchronises them.
They react as the wearer walks and turns, so the skirt looks like a fabric that moves and shimmers.
The smart skirt was created by phone company Nokia, fashion designer Fyodor Golan and design studio Kin.
It's believed to be a world first and has been shown off at London Fashion Week.
