The founder of a celebrity-loved shoe brand rarely wears black. Her formula is simple: Don't blend in.

When Marina Larroudé isn't designing new shoes, she's scouring the internet for something old to wear.

She might be the cofounder of her namesake footwear brand, Larroudé, but she's not interested in chasing the latest luxury drops. Ever been on TheRealReal? She's a regular. She even gets notifications when new (old) Chanel blazers are listed at a discount.

Larroudé's shopping habits are influenced by her life in fashion. She spent a decade in editor roles at Condé Nast, then served as fashion director of the luxury department store Barneys.

Now, the 46-year-old runs the company she and her husband, Ricardo, founded in their dining room nearly six years ago. Since then, the brand has grown to more than 700 employees, opened a factory in Brazil, expanded into accessories and clothes, and gained celebrity fans like Taylor Swift.

As Larroudé's career has evolved, her style has, too. "When I was at Barneys and Condé Nast, I was meeting with designers every day or doing store appearances, so I'd dress up more during my day-to-day," she told Business Insider. "Now, I don't tend to dress up for the office. I am wearing flats every single day, walking up and down our townhouse. Being a founder, I'm more practical."

"I love fashion, and I dress for myself," Larroudé said. "It makes me so happy every day when I get to wear something fun and festive, so I tend to wear lots and lots of color. I only wear black a few times in a year."

During a busy week of meetings, work dinners, and office days, Business Insider documented Larroudé's colorful daily wardrobe. She also shared the fashion formula that helps her get dressed, and some of her favorite pieces in her wardrobe.

There's one thing Larroudé hopes to convey through her daily fashion: "That I have a personality."

"I don't like to blend in," Larroudé said, noting that she wants to be practical and comfortable, but still stand out. If she's wearing a T-shirt and jeans, for example, she'll add a crystal-covered blazer on top and funky heels at the bottom.

"For the longest time, I was a very much a dress person," she said. "Now, my uniform for work is usually printed pants or a skirt with a Uniqlo crew neck — I have them in multiple colors — or jeans or a denim skirt with a special jacket."

She recently wore that combination to work. Larroudé paired a $520 Courrèges miniskirt in light-wash denim with a white T-shirt and a yellow Chanel blazer with pink and blue detailing.
