The actor brought Inside Edition along for the ride.
Stranger Things star Gaten Matarazzo shopped for the perfect outfits at Ted Baker in Los Angeles for Sunday’s Emmys.
Netflix's Stranger Things is nominated for 18 Emmy awards and the star’s date to the show is his older sister, Sabrina.
When the actor, who portrays the loveable Dustin on the show, sported a new navy three-piece suit form the British designer, his sister was floored.
“Dude! Look at you! Look how spiffy! I like it,” she said.
Sabrina opted for a shoulder-baring floral dress.
Gaten said his sister's chosen frock was “awesome,” adding, “You look better than I do.”
They're definitely red-carpet ready for Sunday and will watch Stephen Colbert as he hosts the Emmys at 8 p.m. EDT on CBS.
