The singer has launched a competition to find a new ethical designer - and the winner will design her outfit for an upcoming gig.

The designers are asked to design an outfit that depicts their design philosophy.

We're not sure who designed her outfit.

For this duet, the two designed their outfits, choreography and even their unit symbol (a tarantula).

In designing the outfits, staff aimed to create a look that was relevant and youthful, but not too trendy or hip.
