EXCLUSIVE: Milo Ventimiglia Explains Why He Always Color-Coordinates With Mandy Moore

Milo Ventimiglia looks good in everything (and nothing, as he proved in the pilot episode of This Is Us) -- but only he could look that good in a suit that was custom-made for someone else.
"Luck happened," the 39-year-old actor told ET's Nancy O'Dell on the Golden Globes red carpet on Sunday. "It was a custom suit built by Ralph Lauren for someone -- not here -- literally, like, a civilian in life, and I happened upon it. I said, 'It's built for me.'"
The suit in question is a classic navy blue number, which Ventimiglia paired with a dapper bow tie. Elsewhere on the red carpet, his on-screen wife, Mandy Moore, stunned in a navy Naeem Khan gown featuring a plunging neckline and a sheer cape. The actress told ET's Kevin Frazier that she "always wanted to wear a cape," joking: "I feel like a quasi-superhero!" 
"I was texting with Mandy on our way over. 'Hey, are you in line? Hey are you this...' But then a couple days ago, I said, 'Hey, what are you wearing?' Like, she and I always inadvertently match. We don't even plan it!" Ventimiglia revealed moments earlier.

"Funny enough, if I have stripes on, somehow she has stripes. If I'm in a color, she's in a color," he continued. After her arrival on the carpet, he joked: "That's when you know you're a good television husband and wife!"
Fellow This Is Us stars Chrissy Metz and Sterling K. Brown also seemed to get the color palette memo! The former opted for a royal purple long-sleeved gown with metallic detailing along the waist and cuffs, and the latter, a blue tux with black lapels.

While Brown made headlines for showing off his buff bod on Instagram while getting ready for Sunday's festivities, Ventimiglia posted a video from under the hood of his car.
"Ten years ago, when I was here, I had to water the lawn before I left for the Globes, and just as it happens, I was working on my car," he explained. "So, it kinda became a thing with my friends and I. You put the tux on, but you still gotta do normal life stuff."
This Is Us returns to NBC on Jan. 10 with a sure-to-be-heartbreaking new episode. See the first footage in the player below!
