Britney Spears Fashion Evolution

Her 2002 Grammy Awards dress was among the few iconic looks of the pop princess.

Since her debut in 1999 with her breakthrough song "Baby One More Time," the blonde beauty has often graced the red carpet and award ceremonies.

In the same year, a then-17-year-old singer attended her first-ever American Music Awards wearing a pastel pink dress.

This was followed by the Teen Choice Awards, where the Mississippi-born singer-songwriter wore a pop star uniform.

At the time, Spears opted for a light pink top and bedazzled sparkly flared pants.

Surprisingly, the blonde beauty appeared in an edgier look during the 1999 MTV Video Music Awards.

She was sporting a metallic crop top, flaunting her toned abs, and paired it with a shiny jacket and snakeskin-style flared pants.

In just a year in the music industry, she was nominated in four major categories--Best Choreography, Best Pop Video, Best Female Video, and Viewer's Choice - MTV Russia.

Last but not least is her Billboard Music Awards, where Britney Spears appeared on the red carpet wearing a lilac spaghetti strap gown with sparkly details at the top part.

The singer looked innocent and young with her white shawl.

She then capped off her look with subtle makeup and a simple silver necklace.

This was said to be the pop princess' most classically elegant look to date.
