Matched with a pop-oriented melody, Springsteen's full-throated singing, and a pop-orchestral arrangement, the lyric portrays a series of warm small-town vignettes:

"Girls in Their Summer Clothes" has been cited as a singularly "breezy" song on the album, though A. O. Scott of The New York Times notes: "Not that 'Girls in Their Summer Clothes' is untouched by melancholy. Its narrator, after all, stands and watches as the girls of the title 'pass me by.'" Jay Lustig of The Star-Ledger writes that the song "unfolds gradually and at its own eccentric pace, with the music, and Springsteen's vocals, getting progressively more intense."

It was released for iTunes digital download on January 15, 2008, as a single-like "bundle" consisting of two audio tracks and an accompanying video. As such the "Winter Mix" of the song was presented, which featured a single not doubled Springsteen vocal track, some added or enhanced percussion parts, and similar small changes. In addition to the Winter Mix, a live version was included. The release achieved minor chart success, reaching positions 95 on the Billboard Hot 100, 67 on the Pop 100, and 62 on Hot Digital Songs. It also hit 27 on Billboards Mainstream Rock charts.

The music video for the song (entitled "Girls in Their Summer Clothes (Winter Mix)") was directed by Mark Pellington. Filmed on the Jersey Shore on a cold winter day, it showed girls and women of various ages, interspersed with shots of Springsteen strumming his vintage Gibson J-45 acoustic guitar. The backing E Street Band was not shown. Parts of the video mirrored the song's imagery, especially the diner scene.

"Girls in Their Summer Clothes" was regularly featured on the 2007–2008 Magic Tour, often as the first encore song, although it suffered being dropped during a number of shows in early portions of 2008. One such first leg of tour performance was recorded and included in the January 2008 digital download bundle.
