The singer, 25, turned heads in the figure-hugging ensemble as she strolled through London.
She recently put on a fashion-forward display in a lime green thigh-split gown at the Brit Awards.
And Mabel continued her futuristic wardrobe choices when she headed to rehearsals for BBC Radio 1’s Big Weekend in a monochrome catsuit on Friday.
The hitmaker donned a full face of glamorous makeup for the outing with a sultry copper-toned smokey eye and a flattering nude-lined lip.
She let the outfit speak for itself and kept accessories to a minimum, wearing just a handful of subtle silver rings on her right hand.
Mabel’s career has grown from strength over the past few years, culminating in her scooping the coveted British Female Solo Artist prize at the 2020 BRIT Awards.
Yet she previously revealed she has been battling severe anxiety and depression since her childhood, something which she now accepts will always be part of her.
In a candid interview with GQ, the Don’t Call Me Up hitmaker revealed that she feels liberated after finally learning to embrace her mental health struggles.
