Jill Biden donned the dress she wore for her Vogue cover during a trip to Georgia to push people to get their COVID vaccine.
She toured a pop-up vaccination site at a Savannah high school with Senator Raphael Warnock.
Warnock, one of the state's two Democratic senators who won a January special election, is up for re-election next year and already a top Republican target.
The first lady praised him repeatedly in her remarks.
'You've been in the Senate what less than a year now. But gosh, look at all he has done. You know, you've already delivered for this state,' she said, adding that Warnock invited her to come visit his home town.
Biden wore the blue Oscar de la Renta dress she donned in her cover shoot for the August edition of Vogue, where she was the subject of a flowery profile about her work as first lady. She often repeats her designer outfits.
