The Keeping Up With The Kardashians star was still becoming a household name when she attended the glitzy event in Los Angeles with older sister Kourtney.
Despite appearing on way too many red carpets to count since then, the 34-year-old still thinks her glamorous look at that awards show was her best ever.
Kim told People: "Maybe because I was 20 pounds skinnier and I loved how I looked then... I was wearing some white dress and my hair was pulled back. We had no hair extensions, we just put my hair in a bun and it was a really simple look, and I just thought it was really clean."
The star was speaking to the magazine in her capacity as guest beauty editor in the new issue.
Kim's most recent public appearance was at the BRIT Awards in London last week, where she presented Sam Smith with an award and introduced rapper husband Kanye West's performance.
She shone in a risque little Julien Macdonald jumpsuit on the night.
