The Olympic gymnast was spotted arriving at the Stella McCartney Spring/Summer 2014 show, where the famous designer was debuting her upcoming sportswear collaboration with Adidas, and he certainly dressed to impress.
Wearing a grey and navy blue checked jacket and matching trousers, Louis looked smart and quirky, while also proving that he has a keen interest in fashion and isn't afraid to take risks with his outfits.
He completed his suave ensemble with a crisp white shirt that featured a small chain on the collar and wore a pair of sunglasses to enhance his cool image (despite the weather being grey!)
At the fashion show, 24-year-old Louis was seen chatting it up with Stella - who designed the Team GB kit for the 2012 Olympic Games - and also hanging out with discus thrower Dan Greaves.
Guests watched as the McCartney models re-enacted various sports in the new athletic gear, including cycling, running and yoga.
There were even synchronised swimmers modelling Stella's latest swimwear designs!
Last December, Louis was crowned winner of Strictly Come Dancing and the silver medalist has since hit the road as part of the Strictly tour, as well as performing at the launch of this year's show.
He has also been keeping busy recently by taking part in a summer camp and even found time to go on holiday with his mates.
And with such an action packed schedule, some things managed to slip his mind - such as locking his front door!
Last week he tweeted: "The police just came into my bedroom and woke me up to tell me my front door has been wide open and people thought I had been burgled.. Oops."
