"Just the Girl" was composed by songwriter Adam Schlesinger, best-known for his work with Fountains of Wayne, as well as his career in film and television.

The single was the band's biggest mainstream hit, achieving heavy airplay on top 40 radio in the United States.

Sharp had previously attempted to form a radio-ready pop outfit two decades prior with Candy, and styled the Click Five with identical suits and mod haircuts.

The engineer had previously worked with power-pop band Fountains of Wayne, producing their 2003 hit album Welcome Interstate Managers.

Billboard contributor Chuck Taylor considered it reminiscent of boy-band LFO, dubbing it "just tough enough to be cool, but power poppy enough to have the braces crowd bellowing in unison.

"[14] Jessica Grose of Spin viewed the band's debut, Greetings from Imrie House, as banal and manufactured, but singled out "Just the Girl" as the "only palatable song [...] and that's because Click Five didn't write it.

"[13] After Schlesinger's passing, Tom Breihan at Stereogum described the song as a "processed, professional, infectious teen-longing jam that evoked the Cars and Ashlee Simpson at the same time.

[17] Songwriter Sam Hollander praised the tune as among Schlesinger's best, "brilliantly crafted" and evoking the great "power pop songbook".
