before we go on Christmas break.

-Ooh. -Which means it's time for

that beloved "Tonight Show" tradition.

It's time for "12 Days of Christmas Sweaters."

-♪ "12 Days of Christmas Sweaters," 9 days left ♪

-That's right!

Every show between now and Christmas,

we'll be giving one lucky audience member

a stunning Christmas sweater

from the Countdown to Christmas cabinet.

Now... [ Cheers and applause ]

...since there are only nine shows left,

let's open door number nine.

[ Drum roll ]

Go for it, bud.

Ooh! [ Cheers and applause ]

A phone?

[ Indistinct ]

Uh, is that a phone?

I -- I don't quite understand this one.

Oh, "four birds a calling." Oh, I get it. I get it.

Alright, let's see who goes home with tonight's sweater.

Everyone, look at your seat number.

If I call your number, I need you to jump up

and let me know where you are.

Quest, can I get a drum roll please?

[ Drum roll ]

Who wants me to pick their number? Come on!

[ Cheers and applause ]

427!

Good to see you. How are you? -Hi!

-Welcome to the show. -Thanks! [ Chuckles ]

-What is your name? -Chelsea.

-Chelsea, where are you from?

-Connecticut, but I'm going to school here.

-Hey, alright, good. So, we'll say New York.

Either way, chilly, chilly weather outside.

You have a beautiful jacket there,

but do you have a sweater like this?

-I don't. -Chelsea,

today is your lucky day.

Would you like to try it on? -Sure.

-Yeah, here you go.

Can you hold this for me?

Just put it right over the jacket.

That should be perfect.

[ Cheers and applause ]

Oh, my gosh.

That's beautiful. Oh, my gosh.

It's just gorgeous. Perfect. Oh, my goodness.

You look fantastic. -Thank you.

-Give Chelsea a round of applause.
