Art3mis is the Oasis avatar of Samantha Cook — a skilled gunter whose blog Arty’s Archive is one of the most respected voices in the egg hunt before she becomes a key figure in the resistance against IOI. Played by Olivia Cooke in Spielberg’s 2018 adaptation, Art3mis has one of the most visually distinctive looks in the film: a deep wine red leather moto jacket with painted graphic detailing, black ripped skinny jeans, a black cropped tank, a velvet choker, a punk belt, and the short spiked dark red wig that makes her instantly placeable. Eight pieces for the full build, one ready-made option for kids.

How to Style It

The wine red leather jacket is the piece that places this costume. The shade needs to be a deep, dark red — burgundy or wine rather than bright red or cherry. Art3mis’s jacket in the film reads as a deep, almost blood-red leather that has an intentional, custom-avatar quality, and a jacket that’s too bright loses that specific character. Wear it open over the black cropped tank so the tank is visible at the front, which matches Art3mis’s silhouette in the film. The ripped black skinny jeans add the punk texture beneath — the tears should be at the knee or thigh area to match the film reference.

The short spiked red wig is the most character-specific element after the jacket. Art3mis’s Oasis avatar hair is short, dark red, and styled with texture and volume — it should look deliberately wild rather than smooth. If the wig arrives flat, use your fingers and a small amount of styling product to work it into a spiked, textured shape. The dark red tone of the wig should complement the deep wine red of the jacket rather than clash with it — check both in the same light before the event. The velvet choker sits at the base of the throat and the punk grommet belt goes at the hips over the jeans.

The red fabric paint is for applying the graphic detailing visible on Art3mis’s costume in the film — small painted marks and design elements that give the costume its avatar quality rather than plain street clothes. Practice the application on a scrap of similar fabric first, then apply thin lines or abstract graphic marks to the jacket sleeves or front panel and the jeans. Keep it minimal and deliberate rather than heavy — the paint is an accent detail, not a repaint. Allow the paint to dry completely before wearing to prevent transfer.

Wine Red Shade

The jacket needs to be deep wine red or burgundy — dark enough to read as a deliberate color choice rather than a standard red leather jacket. Check the product photos in natural daylight if ordering online. Bright red or orange-red shades lose the specific character of Art3mis’s avatar aesthetic.

Wig Texturing

Work the wig into a spiked, textured shape using your fingers or a wide-tooth comb with a small amount of styling product. Art3mis’s hair in the film has deliberate volume and direction — a flat, unstyled wig loses the character’s visual energy. Style it before putting it on, then adjust after wearing.

Fabric Paint Application

Practice the red fabric paint on a scrap of similar fabric before applying to the actual jacket. Apply thin lines or abstract marks at the jacket sleeves and front. Minimal and intentional-looking reads as costume detail; heavy application reads as an accident. Allow full drying time before wearing.

Jacket Open vs. Closed

Wear the jacket open so the black cropped tank is visible at the chest. Art3mis’s silhouette in the film uses the open jacket as part of the visual layering. A closed jacket changes the profile and buries the contrast between the red leather and the black underneath.

Belt vs. Choker Priority

If you have to choose between the two accessories for a simplified version of the build, the velvet choker is the more character-specific element. The punk grommet belt is a strong detail but the choker sits at the face level and reads in photos and at a distance more effectively.

Kids Version

The licensed Art3mis costume (item 9) includes the jacket, attached faux shirt, belt, and wig in one purchase — the fastest and most size-appropriate option for younger wearers. The DIY build is better suited for adults and teenagers where individual piece sizing is more reliable.

Group & Couple Ideas

Same Film Duo

Art3mis & Parzival

The central duo of Ready Player One — Art3mis’s dark red leather against Parzival’s denim and blue creates an immediately recognizable film pairing with strong visual contrast. Both characters carry the Oasis avatar quality of their costumes, and the contrast between her punk-influenced red look and his more street-casual blue-and-denim aesthetic tells the story of two very different approaches to the same virtual world. The obvious and best pairing for anyone building this costume.

Oasis Gunters Group

Art3mis, Parzival & High Five

Assemble the High Five — the group of five gunters who ultimately challenge IOI together in the film. Art3mis and Parzival as the visual anchors, with additional group members representing Aech, Sho, and Daito. Each character has a distinct enough Oasis avatar look that a group of five can cover all of them with strong individual visual variety. A strong concept for a larger group that wants a complete film ensemble rather than just a pair.

Spielberg Universe

Art3mis & Burt Fabelman

A director’s-cut pairing from two different Spielberg films — Art3mis from Ready Player One alongside Burt Fabelman from The Fabelmans. The visual contrast between Art3mis’s sci-fi virtual world punk aesthetic and Burt Fabelman’s 1950s suburban dad look is significant, and the shared Spielberg connection gives the pairing a clear thematic anchor for film enthusiasts. A strong two-person concept that rewards anyone who knows both films.

Spielberg Characters Group

Art3mis, Parzival & Claire Dearing

Three characters from three different Spielberg-produced or directed films — Art3mis and Parzival from Ready Player One, and Claire Dearing from Jurassic World. Three completely different aesthetic registers — virtual world punk, street-casual gunter, and Jurassic Park operations director — that create a group unified entirely by their director connection. A niche but rewarding concept for a group of dedicated film fans.

This is the fastest option for younger wearers and ships quickly. The DIY build using individual pieces is better for adults and teenagers where sizing needs more flexibility.

Art3mis’s leather jacket is a deep wine red or burgundy — dark and saturated rather than bright or orange-red. The darkness of the shade is part of what makes the jacket read as a deliberate Oasis avatar design choice. Look for descriptions like “wine red,” “burgundy,” or “dark red” when ordering; avoid anything described as “cherry” or “fire” red.

Parzival is the natural and strongest pairing — the central duo of Ready Player One with strong visual contrast between Art3mis’s dark red leather and Parzival’s denim-and-blue look. For a broader group, the full High Five ensemble covers the other three main characters of the film. For a thematic Spielberg group, Claire Dearing from Jurassic World and Burt Fabelman from The Fabelmans create a director-specific ensemble.
