Zac Posen would "love" to design a sportswear line.
The 35-year-old American fashion designer has admitted he is "interested" in launching an athleisure clothing range, which would include jersey tops for men and women, because he likes the way workout garments shape the body.
Speaking to Marie Claire in a live vlog, which was aired on their social media page on Tuesday (07.06.16), the creative mastermind said: "I love athleisure. I would be very interested in doing an athleisure line because I like the ergonomic lines on the body and how they're cut, and I think it would really work well in jerseys and yoga gear and workout gear, men's and women's."
However, the fashion mogul - who was named the Creative Director of the long standing men's clothier Brooks Brothers in 2014 to modernise the brand and evolve their womenswear collection - has revealed he has not worn trainers for 15 years around New York, and will only don a pair of trainers when he is in the countryside.
He explained: "No sneakers in the workplace. On the train its fine you can have a working girl moment.
"Some people like the idea of heels high femininity and power.
"I have sweatpants that I wear, I wear t-shirts in my own world. I do have a pair of sneakers I wear in the countryside, not for fifteen years have I worn them in New York city.
"I wear also these little slippers, they are comfy."
And Zac - who designed Claire Danes' Met Gala Cinderella-esque dress to follow this year's Manus x Machina: Fashion in an Age of Technology theme - has revealed the show stopping gown, which had 30 mini battery packs intricately sewn into the fiber optic organza dress to make the garment glow in the dark, stayed glowing for 10 hours.
Speaking about the unforgettable creation and whether the 'Homeland' actress overheated with the electrical device hidden underneath the garment, he said: "No because they are low power. But they are such a low wattage battery that it creates to create light, it's an LED so no light bulbs underneath, no Christmas trees underneath, no neon.
"[It worked] switch by switch. Sections.
"It also collects light, any light that hits it creates colour within it.
"The lighting lasts for like 10 hours, so I think that's a good long evening, much longer than getting and arriving to the Met ball. So we were fully illuminated until we were in the car in the evening she was still lit, the gown was still lit."
