The 42-year-old radio presenter has announced he will be expanding his Ryan Seacrest Distinction fashion range to include an Autumn/Winter 2017 sportswear line, which will "coordinate" with the tailored suits section in Macy's, and it will be available to buy in the American department store in September this year.
Ryan has admitted his designs were inspired by his lifestyle and were created to allow "more freedom and flexibility" in menswear garments.
Speaking about his latest venture to WWD Online, he said: "Lifewear is inspired by how I live. Our fall collection is an interpretation of how I actually dress these days. I may wear a blazer over a T-shirt or denim button-down shirt, or a more casual pant with a dress shirt and tie, or jeans with a sport coat with sneakers.
"More freedom and flexibility in their dressing because that's where our culture is today. Everything needs to go together effortlessly. The RSD collection pieces are easy and comfortable, in addition to be being carefully tailored.
"We look at it as a real business and its success matters to us. I try to have that approach in everything I do, whether it's the radio show, hosting or fashion. All the ventures are equally important."
The American television host has been praised as "the definition of a modern man" by the popular retailer, whose "dynamic" and busy work schedule led him to combine "great versatility and fashion" with his creations.
Speaking about the star, Macy's executive vice president, Karin Darmanin, said: "Ryan Seacrest is the definition of a modern man, building a multimedia empire all while impeccably dressed. His dynamic life inspires the designs behind Ryan Seacrest Distinction. Ryan knows the importance of day-to-night dressing, as he navigates between his morning radio show, daily business meetings and red carpet events. His collection for Macy's now includes essential pieces designed to coordinate with the suiting, that offer great versatility and fashion for a modern career."
This news comes a few months after Ryan - who helmed 'American Idol' for 14 years from 2002 up until last year - released his debut collection for the brand last summer with an athleisure line to celebrate the Olympic Games, which was held in the Brazilian capital Rio de Janeiro in 2016.
Speaking previously about his first drop, he said: "The Rio collection was a limited run, but since then, we brought on Matteo [Gottardi] to really focus on the distinction part of Distinction and why it's special."
