Matt Lauer's plaid jacket became a Twitter hit, with a little help from Ann Curry and Savannah Guthrie.

Ann started the show saying that Matt's jacket reminded her of Johnny Carson's style. Matt agreed. "This is kind of what would happen if Johnny Carson were a guest star on 'Mad Men,'" he quipped. 

And that was all the prompting Savannah needed to continue the joke. "I felt it was our collective responsibility to keep it going all morning," the avid tweeter told TODAY.com. "What better way than to engage on Twitter, especially since Matt doesn't tweet?"

Savannah set up the Twitter account @MattPlaidJacket (shockingly, @MattJacket was already taken) and started a stream of jokes. And it's already catching on with almost 200 followers.

Tweeters also weighed in on Matt's fashion choice. Here's a selection of our favorite messages: 

Despite the good-natured ribbing, Savannah says she likes the jacket. "He pulls it off," she wrote.

Seeing red: TODAY's Savannah Guthrie, Hoda Kotb, Kathie Lee Gifford and Natalie Morales take part in Wear Red Day on Feb. 3.

Red isn't just the color of seduction. It's also the shade of supporting women's health.

Today, the first Friday of February, is Wear Red Day, which promotes awareness of heart disease, the number one killer of women. (It's also American Heart Month). On this day, ladies are encouraged to wear anything red, be it a dress, shoes, scarf — or even just a pin.

"I learned late in life that my heart health is my greatest asset, which is why I celebrate National Wear Red Day," said Star Jones, TODAY contributor and National Volunteer for the American Heart Association. "Join me."

In honor of the campaign, TODAY's lovely talent donned the striking crimson hue this morning. Join them in their fight against the disease by sharing your own photos! If you're in the chosen color today, upload a photo to the Wear Red Day Facebook page and TODAY's Facebook wall!

'Tis the season ... for ugly Christmas sweaters!

Once an endearing gift from a well-meaning grandma, hideous jumpers have become a fad, spawning booming businesses, Facebook groups and sweater parties. 

Savannah picked out some especially gnarly knits for our anchors and a few guests (Brian Williams and Matt Damon got roped in, as well as our crew and the entire control room). Check out the pics below and vote in our poll: Whose sweater is the ugliest?

Upload your own photos of ugly Christmas sweaters. TODAY.com posted some of the worst offenders.

We know that Savannah is multi-talented! Beyond her on-camera skills, she has a law degree, can rock out on the guitar and expertly answers your Facebook questions. But how would she fare in the fashion world?  

She had the chance to test her catwalk competence when powerhouse designers Georgina Chapman and Keren Craig, founders of Marchesa, invited her to show off their threads during New York City's Fashion Week.

The Marchesa brand, which specializes in high end woman's wear, was a perfect fit for the sophisticated Savannah. Yet, every newbie needs a model mentor! Luckily for Savannah, supermodel Karolina Kurkova stepped in to be her coach.  

So will Savannah ditch morning television to pursue this fashionista path?

"Heidi Klum has nothing to worry about." Savannah said on TODAY. She'll stick with the familiar walls of studio 1A.

Check out the video above, and let us know in the comments what you think about her debut!

Most TODAY viewers wonder whether or not the anchors choose their own wardrobe.  Last month, Natalie Morales dished that she does, in fact, wear her own clothes, adding, "I'm a good shopper!"

This morning on TODAY, Natalie and Savannah Guthrie revealed another oft-pondered viewer question: Do the anchors coordinate their outfits prior to the show?  

As evidenced by their clashing patterns, the answer is no. Jeff Lewis of Bravo's "Flipping Out" even had a few critiques of their choices. 

And Lewis wasn't the only one handing out style commentary. After Natalie read the news at 8, Matt quipped that her dress looked like it was from "The Flintstones." "I knew it was coming!" Natalie said. (Watch Matt give Natalie a joking zing in the clip below).

The truth is, Natalie did not shop at a Bedrock boutique for her perfectly lovely polka-dotted shift. It's a Kay Unger dress, topped with a cardigan from J. Crew. So take that, fashion peanut gallery!
