As a child, Jeon enjoyed expressing herself through clothes and fashion. Her personality extended to her own style, including a Louis Vuitton bag she customized with a drawing of a unicorn, which she believed resembles herself. Jeon commented, "I like monogram patterns and colors. When I think of the monogram bag my mother carried about 10 years ago, I still think it's cool." For her single "What You Waiting For", Jeon was involved in the planning and styling process for her music video and worked closely with Serian, the current director of Vogue Korea. She selected looks portraying confidence and chose to wield a sword in the video to complete the "badass" look, with a hidden meaning relating to her birth name "Ennik", which means "sword" in Old Dutch/Old Frisian. Jeon also often invests her time in DIY projects, enjoying taking clothing apart, putting the pieces back together, tearing them apart again, and repeating the process again as part of her experiments.

Jeon usually records two versions of songs she writes, each in a different language. After grasping the "feel" of the song in English, the lyrics are changed to Korean. She explained, "For example, if the lyric is 'orange', it will be changed to 'how long' (in Korean), making similar pronunciations". The original lyrics to the hook of her single "Dumb Dumb" were "Imma say it like it is / cut the bullsh*t / you dumb dumb"; in the official version, they have been translated to Korean. Jeon attributed the longer wait between comebacks to this recording process and vouched it improves the result.{{cite episode|number=|title=Somi Twitter Blueroom Live Q&A|series=Twitter Blueroom Live|url=https://twitter.com/i/broadcasts/1LyxBdqWyNEGN|time=28:09|network=Twitter|date=August 5, 2019|access-date=August 11, 2021|archive-date=August 11, 2021|archive-url=https://web.archive.org/web/20210811073954/https://twitter.com/i/broadcasts/1LyxBdqWyNEGN|url-status=live}}

As a soloist under The Black Label, Jeon has gained greater artistic and creative control over her music and career. She stated, "There are a lot of great producers, songwriters, creatives and people I truly respect here. I've matured both professionally and personally a lot by learning from them and seeing how they do things up close. But there is still a lot to go. I'm still definitely learning". She credits Teddy as an important mentor in her growth as a songwriter: "Every songwriter and producer has their own way to express themselves artistically and Teddy is helping me to find my own way."

During her childhood, Jeon's favorite musicians were Cyndi Lauper, Rihanna, and 2NE1.{{cite web|title=Somi on Conversing with Cats, Cheesy Lasagna, and "Dumb Dumb"|url=https://www.interviewmagazine.com/music/somi-on-conversing-with-cats-cheesy-lasagna-and-dumb-dumb|website=Interview|last=Hullander|first=Meghan|date=August 16, 2021|access-date=August 18, 2021|archive-date=August 19, 2021|archive-url=https://web.archive.org/web/20210819144506/https://www.interviewmagazine.com/music/somi-on-conversing-with-cats-cheesy-lasagna-and-dumb-dumb|url-status=live}} Growing up, Jeon also listened to the music of South Korean singer Seo Taiji, whom she described as an artist who "rocked the music industry", thanks to her mother's influence.{{Cite news|script-title=ko:[POP이슈]"언니라 불러"..'최파타' 전소미X제아, 사제지간→흥자매로 매력↑|trans-title=[POP Issue] "Call me Unnie" ...
