 After its release, "The Real Thing" received generally favorable reviews from critics. Critics appreciated the "vintage" production of the song and labeled it a stand-out track on the album, while also noting its New Order influence. Stefani performed the single throughout her 2005 Harajuku Lovers Tour in a vintage red bathing suit along with a group of breakdancers and the Harajuku Girls. The live performance was praised and compared to Madonna and Cyndi Lauper.
