In a partnership with Refinery29, the WPP-backed site aimed at young women, the pop-up will be set inside "a human-sized interpretation of a snow globe".
The activation will also feature an arcade grab machine stocked with The Outnet.com gifts and discounts, a gif camera, instore competitions, and Facebook Live events with Refinery29 editorial staff.
The activation is running in London's Soho between 8 and 17 December.
Kirsty Hathaway, Refinery29’s creative director of Europe said: "We are constantly looking for the most exciting ways we can speak with - and listen to - our audience.
"Immersive events continue to be one of the best avenues for Refinery29 to connect with women around the world, so to work with The Outnet.com to use art as inspiration and to reimagine the timeless tradition of unveiling holiday windows while we directly engage women is an ideal opportunity for us all."
