When Michelle Obama wore Jason Wu's gorgeous one-shoulder gown to her first Inaugural ball back in 2009, it was the first time many of us had heard of the designer.
Four years later, the fashionable FLOTUS has the nation talking about the young designer yet again, having worn his eye-catching ruby red floor-length dress to her second ball.
But if you're still as clueless about Wu as you were four years ago, we're filling you in on five things you need to know about the first lady's designer darling:
1. Toy Story: Though he dresses some pretty famous faces today, Wu started out designing clothes for toy dolls. That's right, back when he was a mere 16 years old, Wu created tiny outfits for European company Integrity Toys. Apparently, even his pint-size wear was pretty fierce, as he was promoted to creative director a year after joining the company.
2. Award-Worthy: A little over a year after he made headlines for creating Obama's first inauguration gown, Wu was in the news again for receiving the prestigious Council of Fashion Designers of America's Swarovski Award for his work in womenswear. Not bad for a designer who hadn't even hit 30, huh?
3. Wowed by Wu: The first lady isn't the only celebrity to have been, ahem, Wu-ed by the designer. Leading ladies Diane Kruger, Camilla Belle Ginnifer Goodwin, Blake Lively, Emma Stone, Jaime King and Emily Blunt also adore his stunning creations. King is such a huge fan that she's been known to consult the designer before hitting a big event and tries to include at least one of his pieces in her red carpet ensembles.
4. Right on Target: Celebs aren't the only fans of Wu's designs. In February of last year, his limited-edition 53-piece collection for Target sold out just hours after it hit the retailer's site and shelves.
5. More Wu for You: Earlier this month, Wu expanded his growing empire with a moderately priced collection, Miss Wu. Available exclusively at Nordstrom, the 40-piece capsule collection offers more affordable options than his eponymous line, like a pretty tie-neck blouse for $195.
