"Nancy Reagan -- A First Lady's Style" is a year-long exhibit that opened to the public Saturday.
Featuring 80 ensembles highlighting Reagan's various roles as wife, hostess and public servant, the dresses are showcased on Size 2 mannequins created for the show, the Los Angeles Daily News reported.
"It's more than we ever imagined it could be," library spokeswoman Melissa Giller said. "It is about her essence."
