Rob Kardashian's new business venture is unexpected to say the least.
The 27-year-old Keeping Up with the Kardashians star is coming out with a new loungewear line, which also includes onesies for men.
"Coming soon to select Macy's stores, @robkardashian's loungewear line @arthurgeorge87!!," Kris Jenner posted on Instagram Tuesday, obviously proud of this star-print onesies design. "Love you @robkardashian!! #ProudMama."

She also showed some love for Rob in this recent post, calling him her "everything."
Rob, who's perhaps more famous for his fluctuating weight these days, already has his Arthur George socks line, which sells at high-end department chains like Neiman Marcus and Nordstrom.
His famous younger sisters Kendall and Kylie Jenner have both modeled for the line, with 17-year-old Kylie especially raising eyebrows for this pants-less look.
... Any chance we'll be seeing Kanye West in a pair of Arthur George onesies?
But if you think Rob's new designs are pretty questionable, let's not forget some of his standout sock designs, which include sayings like, "Stay trill," Thug life, and "MILF."
