"Sweater Weather" is the lead single from The Neighborhood's debut EP I'm Sorry... and it is also featured on their debut full-length album I Love You. "Sweater Weather" is one of The Neighborhood's most successful tracks, peaking at #14 on the Billboard Hot 100 charts in December 2013 and spent 11 weeks at #1 on the alternative charts. The music video for the track reached 100 million views in December 2015, when the video was merely two years old. "Sweater Weather" is the first song the band had ever written together, composed during their first practice, around a year before its release. Frontman Jesse Rutherford recalled the day: "It was just a really special moment and it felt special before anybody said it was special. When we first wrote it and showed our families and some friends that we trusted their opinion around town or whatever, it was just a different reaction than we’d ever seen someone have to our music."
