The demo version of this song was originally included on Grace's debut EP, Memo. In September 2015, she released the official single version. A third interpretation, which was remixed by Naughty Boy after Grace met him in Christmas 2015, was included on the Australian's debut album, FMA. Grace recalled to iHeartRadio:
"When we first really started [on 'Boyfriend Jeans'], it was just like a crappy demo on a voice note. It was really hard for us to find a new version of it. I think everyone had like demo-itis and loved the original so much because it was super raw and it was in the moment and it was recorded in my bedroom. To recreate that you don't always get it right, so Naughty's version was the first remix that we had heard that we were like, 'This feels good. It's different. It shows the song in a different light,' which was cool, and I love it. It's my favorite version done to date of the demo."
