During her time with Prada, she designed the lavender dress that Uma Thurman wore at the 67th Academy Awards in 1995.
Bronwyn Cosgrave in her 2006 book Made For Each Other: Fashion and the Academy Awards describes the dress as being beautifully crafted and admired for weeks afterwards by the media.
[10] The 2000 book Fashion: The Century of the Designer 1900–1999 credits the dress for opening up Prada in Hollywood saying, "...Uma Thurman appeared at the ceremony in a lavender gown and stole, catapulting herself onto magazine covers and bringing Prada to the attention of Hollywood.
"[11][12] Variety magazine's 2003 Complete Book of Oscar Fashion described it as "the gown that launched a thousand imitations"; and indeed, a year later, Nicole Kidman wore a Prada dress of an identical colour at the 68th Academy Awards.
