Billionaire Mark Cuban Was Asked By Fellow 'Shark Tank Star,' 'With All Due Respect, Why Do You Dress Like A Slob?' — He Responded: 'Because I Can'

Most billionaires tend to look like billionaires. Polished suits, expensive shoes, and watches that cost more than a car. Mark Cuban? He'd rather roll into a room in a T-shirt and jeans. And if you've ever wondered why he doesn't bother dressing up—he's already explained it in the most Cuban way possible.

In an October TikTok posted to his own account, Robert Herjavec—another ‘Shark Tank' star and Canadian entrepreneur, reflected on an conversation he once had with Cuban regarding his fashion choices. "I've known @Mark Cuban for a long time, and from what I remember, he's never been the best-dressed guy in the room—always in t-shirts," Herjavec said. 

So, one day, he asked Cuban,"With all due respect, why do you dress like a slob?"

Cuban could've gotten defensive. He could've snapped back or rattled off some explanation. Instead, he didn't flinch—he just shrugged it off with five words that said it all:

"Because I can."

Sure, "Because I can" sounds like something a defiant kid might say—but coming from a billionaire, it was more like a mission statement.

For anyone who watched Cuban during his ‘Shark Tank' years or followed his entrepreneurial ventures, it's no secret he's never been big on traditional business norms. He's famously said he avoids calls and meetings whenever possible and handles most things by email. Cuban built his career by getting results—not by logging hours in boardrooms or stressing over dress codes.

Herjavec later reflected on that moment and admitted it stuck with him. At first, he thought Cuban was just being, well… Cuban. But over time, he realized the deeper meaning.

In other words, the guy in the T-shirt already won.

Herjavec even shared another gem he picked up from watching Cuban in action:

"If you walk into a room and there's 20 people in suits and ties and one person in a T-shirt—that's the one with the power. That person worked their ass off to get to a position where they can wear whatever they want."

It's a mindset that's resonated beyond just Cuban's circle. His casual style and refusal to play by old-school rules reflect a bigger shift in how success is measured today. Forget appearances. It's about results, innovation, and—when you've really made it—the freedom to just be yourself.

Cuban's "Because I can" has basically become a rallying cry for entrepreneurs and business rebels everywhere. Not because they're lazy about their wardrobe—but because they're too busy building something bigger to care what anyone thinks.

And honestly? That might be the sharpest power suit of all.
