It comes as pictures of Oscar-nominated star Margot Robbie were released to promote the upcoming flick Once Upon a Time in Hollywood.
Tate was famously murdered by followers of the cult leader Charles Manson while eight-and-a-half months pregnant in an atrocity that shocked the world.
Also killed at the Los Angeles mansion where Tate lived with husband Roman Polanski was celebrity hairstylist Jay Sebring, coffee heiress Abigail Folger, writer Wojciech Frykowski and friend Steven Parent.
Polanski was out of the country at the time.
Manson, along with other members of his cult, was jailed for life and died in custody in November last year.
Tate’s wedding dress will be the star of the line-up at the ghoulish auction, and has a starting price of almost £20,000 ($25,000).
A set of blue floral canvas and leather carry-on luggage monogrammed «ST» will also go under the hammer — and was photographed being used by Tate and Polanski as they returned from their honeymoon in 1968.
Tate’s chocolate mink swing coat designed by «Fuhrman’s Beverly Hills» with an asymmetrical collar and fur puffs for buttons could sell for as much as £31,000 ($40,000), auctioneers believe.
Darren Julien, the president of Julien’s Auctions said: «Julien’s Auctions is proud to present this auction event that celebrates the beauty and grace of one of Hollywood’s brightest stars of the 1960s, Sharon Tate.
«We honor Sharon Tate’s life and loves in this personal collection that captures the style of a woman whose life was cut way too short and has long been overshadowed by an unspeakable tragedy.»
Model Tate was scouted in Italy when she was just 18. Her first major starring role was in the 1966 occult classic Eye of the Devil.
The screen siren met director and future husband Roman Polanski when she was cast in The Fearless Vampire Killers in 1967 and married him in London the next year.
Their star-studded wedding included guests such as Joan Collins and Michael Caine, who partied with them at The Playboy Club after the ceremony.
Her most famous role and acclaimed performance came as Jennifer North in the 1967 cult classic film Valley of the Dolls, which earned her a Golden Globe Award nomination for Best New Actress.
Her final film role was in The 13 Chairs, also known as 12+1, which was released posthumously in 1969.
