The new project was announced via a teaser video clip shared on the official Telfar Instagram page on Thursday.
At just five seconds in length, the video shows a man turning to face the camera in a black, skin-tight, crew-neck t-shirt with a hybrid design of the Ugg and Telfar logos reimagined in rhinestones.
The clip was followed by a second video showing the brand’s founder and designer, Telfar Clemens, wearing a number of pieces that may be from the new collaboration, including the brand’s signature boots, a fur hat, shearling-lined vest and neutral sweater.
“If something feels good and doesn't look right, that's when I know I'm on to something,” he says in the clip.
“When you make clothes at the end of the day, you're touching people, you're all over people's bodies.
“And if I'm going to touch people, I want them to feel good,” he says.
Clemens’ admiration for the California lifestyle brand goes back to 2010, when he created his own take on the iconic boot, a move he replicated in 2014.
In a statement, he said: “I find UGG really sexy—a soft kind of rugged.
"I have made unofficial, unauthorised UGG boots in two shows already dating back to 2010.
“So, I’ve always been obsessed [with] a certain kind of ubiquity and when something really unique ends up on everybody."
Clemens added that he wants to “get down to the DNA of UGG and see what genes we have in common”.
Andrea O’Donnell, president of fashion lifestyle for Deckers Brands, of which Ugg is a sub-division, said: "Telfar is exceptional; a true pioneer and visionary and one of the first designers to believe that being unapologetically yourself is sexy.
“At UGG, we believe in the same thing, and that fashion can be real, democratic and aspirational all at the same time.
“This collection will be the perfect expression of our shared beliefs.”
Telfar is the first creative in Ugg's Feel You line-up, with two further London-based designers set to be announced later this month.
