From their time playing the role of Michelle Tanner on "Full House" to sitting front row at New York Fashion Week, Mary-Kate and Ashley Olsen have made a name for themselves as designers, actresses, and veritable fashion icons.
From the 1990s up until today, the Olsen twins' style has evolved. However, a few iconic looks stand apart from the rest.
In honor of the Olsen twins turning 34 on June 13, here are 15 of Mary-Kate and Ashley Olsen's most iconic fashion moments.
Though Mary-Kate and Ashley are fraternal twins, they often wore matching outfits in their early acting years that made it difficult for people to tell them apart.

Even as young child stars, the Olsen twins knew how to accessorize.

At another Hollywood movie premiere, the twins decided to coordinate their looks once again.

Mary-Kate wore a floor-length, embroidered white gown while Ashley wore a high-low gold dress with a shimmery overlay and a pastel pink belt.
The theme for this year's gala was the history and impact of Chanel, though neither twin wore designs by the fashion house. Instead, Ashley's dress was designed by Oscar de la Renta and Mary-Kate's was vintage.
However, by the time New York Fashion Week rolled around in 2012, Mary-Kate and Ashley were back at it again with matching all-black ensembles.
