The `Price Tag` hitmaker suffered a broken left foot earlier this year and she now plans to ditch stacked shoes because the injury has made her value comfort over style.
She said: "The best fashion lesson I`ve learnt is don`t wear shoes you can`t walk in because it ruins your night. Believe me, since I broke my foot and haven`t been able to wear heels, my legs aren`t achy.
"I don`t think I`ll wear heels again. I might just get some really blinged up Skechers trainers."
Jessie - who injured her foot by jumping off a stage during a concert rehearsal - is known for her outrageous fashion choices but no matter how wacky her clothes seem, the pop star always ensures her outfits are practical.
She told Now magazine: "My fashion mantra is always wear something you can go to the toilet in. I need to remember that."
The singer enjoys pushing the boundaries of style, but she has no plans to copy other female fashionistas like Lady Gaga and Gwen Stefani.
She added: "I`m 23 so I like pushing boundaries, but not to the point that I`ll go to an awards ceremony in a meat dress or as a Harajuku girl.
"People compare me to Lady Gaga and Nicki Minaj but I`m nothing like them at all."
