Who: Celine Dion

When: January 23, 2019

Wearing: Ronald Van Der Kemp

Why: Valentino's collection may have brought her to tears, but we're emotional over Dion's razor-sharp Ronald Van Der Kemp suit. In fact, our favorite time of the year is when Celine Dion attends Paris couture week and pulls out all the sartorial stops. Getty Images

Who: Naomi Campbell

When: January 17, 2019

When: January 14, 2019

Wearing: Aritzia dress, Gabriela Hearst bag, Sentaler coat, Stuart Weitzman shoes

Who: Amandla Stenberg

When: January 09, 2019

When: January 6, 2019 i

Wearing: Miu Miu, Anita Ko jewelry

Who: Lady Gaga

When: January 8, 2019

Wearing: Ralph Lauren

Why: Lady Gaga's periwinkle number at the Golden Globes was a moment, but let's talk about her crystal-embellished tuxedo look at the National Board of Review Annual Awards Gala too. It's still unclear whether her pom accessory serves a functional purpose, but we support her 100 percent. Getty Images

Who: Regina King

When: January 6, 2019

Wearing: Alberta Ferretti dress, Messika jewelry

Why: Statuesque doesn't even begin to describe Regina King at the Golden Globes this week. Her dazzling look is a tall glass of sparkling rosé, and that's about the highest praise we could give an outfit. Getty Images

When: January 01, 2018

When: January 3, 2019

Wearing: Cushnie

Who: Yara Shahidi

When: January 02, 2019

Wearing: Nanushka top, TRE by Natalie Ratabesi jeans, Casadei heels

Who: Emma Stone

When: January 3, 2019
