Argent specializes in women's suits. In recent years, the startup has dressed politicians like Kamala Harris and Nancy Pelosi, actresses like Amy Poehler, and even former royalty like Meghan Markle.

The brand also received investment from Peter Thiel's venture capital fund, Founders Fund.

Argent's founder, Sali Christeson, said after years of dressing down during the pandemic, people now have "sweatpant fatigue" and noted that the brand has never seen the kind of demand its seeing in 2023.

Alaina Hartley, an investor at the venture capital firm Greycroft, told Insider that one of her picks for a work event was this olive green suit from Argent.

Hill House Home is a lifestyle brand that launched in 2016 and became particularly well-known in 2020 for its "Nap Dress."

In July 2020, Kayla Marci, a marketing analyst at retail data analytics firm Edited, told Insider, "With people continuing to work remotely, plus the high levels of unemployment post-COVID, people will be spending more time indoors, contributing to the rise of the 'homewear' wardrobe where this dress falls under."

A few years later, the brand continues to thrive as people adjust to a post-pandemic new normal. In September 2022, Hill House Home raised more than $20 million in funding, according PitchBook.

Alexa von Tobel, founder and managing director of venture capital firm Inspired Capital, told Insider that Hill House Home is among her favorite brands.

Tibi is a womenswear brand that was founded by designer Amy Smilovic in 1997, according to its website. Over the years, the brand has become known for its power suits.

Yet when the norms of work fashion changed during the pandemic, Smilovic pivoted to a new strategy.

In December 2020, she launched a video series called "Style Class" where she advised viewers about how to clean out their closet and find their personal style. As of September 2022, Women's Wear Daily reported that the series had increased Smilovic's gross profit by more than 300%.

The series is now into its fourth season, and has won Tibi many new supporters.

She added, "While they do take a few wears to break in, she says that "Once you soften the stiffness in the insole, they'll become one of the most comfortable shoes you wear."

In 2023, the brand has endured, as multiple founders told Insider that they're a fan of Veja sneakers for everyday wear.

The brand is not for the faint of heart — or budget. Still, founders told Insider that's among their favorite workwear lines.

Tanner Graham, the cofounder of brand agency General Idea, said, "Bode creates incredible one-of-a-kind clothing. It's another brand that does a great job at mixing references of the past, with clothing that is very of-the-now."

"Many of their products are made in limited quantities using vintage fabrics. Every item feels like has a storied past but made relevant for today," he added.

At the time, He also said, "When we thought about launching ADAY, we were just two women who knew nothing about fashion design."

Since then, the brand has become popular with busy startup founders.

Stephanie Estey, cofounder of sexual health startup TBD Health told Insider, "ADAY is the only thing I wear. They make easy, comfortable and looks put together without much effort."
