Sharon Tate's costume blends biographical research and fictional choices. The white miniskirt and black jumper seen on the cinema visit should be distinguished from the yellow outfit at the Playboy Mansion party.
Two outfits worth distinguishing
Sharon Tate's visit to the cinema features a combination of a white miniskirt, a black roll-neck jumper and white boots. The skirt in that sequence is not yellow. Yellow belongs to another striking outfit, used during the party at the Playboy Mansion. Separating the two looks makes it possible to recognise how the film adapts Sharon's presence to different situations without reducing all her clothing to a single promotional image.
Arianne Phillips explained that the black-and-white outfit was inspired by photographs of Tate. The designer also worked with Debra Tate, the actress's sister, and was able to see garments and family references. That research provides a concrete basis, but it does not turn every scene into an exact reproduction of a historical day. The costume uses documents to build a cinematic presence within situations organised by Tarantino.
The contrast between the dark jumper and the light garments makes the figure easy to read as Sharon walks through Westwood. The silhouette combines a relatively covered top with the lightness of the miniskirt. The boots visually extend the movement of the legs and place the outfit within a recognisable 1960s fashion. The clothing allows the walk to have its own energy before the character enters the theatre.
The scene of Sharon watching The Wrecking Crew then alters the relationship with those clothes. As she sits down and settles in, the public figure becomes a spectator enjoying other people's reactions. The costume remains recognisable, but the body inhabits it with a different intimacy. The film gives importance to that change of attitude: an actress can watch her work without continuously maintaining a social presentation pose.
The yellow party look and the memory of Ossie Clark
The yellow outfit at the party is a vintage Ossie Clark piece selected for the film. Phillips specified that it had not belonged to Sharon Tate. That distinction is essential: the designer was part of the actress's style references, but the origin of a specific garment should not be invented to reinforce a sense of authenticity. The choice combines historical affinity and suitability for Margot Robbie's body.
The arrival at the party includes a long coat inspired by one made of python skin that Tate had worn. For the film, a replica was made using imitation material. The coat and the inner outfit produce a visible transformation when Sharon takes it off. The outer layer, longer and more enveloping, gives way to a luminous figure that can dance freely within the celebration space.
Here, yellow has a different function from the black and white of the walk. It brings a warm and open presence to a group scene, where music and dancing organise much of the attention. The reading does not require the colour to be given a universal meaning. Its effect depends on the lighting, the bodies surrounding Sharon and the way Robbie moves among them.
The clothes also take part in the decision to show the character enjoying herself. The film lingers on her dancing, her curiosity and her relationships, while the viewer's historical knowledge may project a threat onto these images. The costume does not remove that tension, but it helps Sharon to have a present life on screen. Yellow belongs to a specific party before becoming a memory associated with the fate of a real person.
Researching a person and building a character
The relationship between the historical Sharon Tate and her portrayal requires care because photographs of a celebrity can seem enough to know her. Clothes provide information about tastes, proportions and contexts, but they do not contain a whole personality. Phillips and Robbie work from those references to build an interpretation. The result can evoke Tate without claiming direct access to every thought or emotion she had during her life.
The character of Sharon is expressed in many scenes through movements and reactions rather than long dialogues. The costume helps maintain differences between going out, dancing, resting and working. A garment chosen for a party does not create the same relationship with the body as one worn during a day around the city. Those variations lend everyday depth to someone who could otherwise have been reduced to a motionless iconic image.
The cinematography completes that construction through light on fabrics, skin and colours. The white of the boots, the black of the jumper and the yellow of the outfit do not appear in isolation from the interiors and the streets. The film integrates them into a city of bright surfaces and dense shadows. The shared work allows the clothes to be visible without turning every appearance of Sharon into an autonomous fashion display.
The costume as identity works best here when the difference between reference, recreation and original period garment is preserved. The Ossie Clark outfit was sourced for the film; the coat was recreated; the black-and-white combination recovered a documented look. Those decisions produce continuity without requiring everything to come from Tate's real wardrobe. Precision in the details makes it possible to appreciate Phillips's work while also keeping Sharon as a person who moves, observes and enjoys herself within the fiction.
