Ms. Casey’s wardrobe in Severance reflects the cold, unnervingly curated environment of Lumon Industries. Everything she wears looks deliberately polite, sterile, and slightly out of sync with modern corporate fashion, leaning into mid-century silhouettes with subdued color palettes.
Putting this costume together comes down to choosing between her two primary screen looks: the tailored burgundy dress she wears during wellness sessions, or the layered office separates centered around a high-contrast collar and textured skirt. Both options rely on modest cuts and clean lines rather than elaborate construction.
The Layered Office Separates
Her most recognizable daily ensemble pairs a structured White Peter Pan Collar Blouse under a fitted Black Sweater. The rounded collar needs to sit flat against the neckline of the knitwear, extending smoothly over the crew opening so the stark white fabric frames the neck cleanly. Keeping the sweater relatively fine-gauge prevents bulk around the shoulders and keeps the profile neat.
For bottoms, a tailored Tweed Skirt anchors the lower half. Lumon’s dress code heavily favors structured textiles with subtle woven patterns in greys, browns, or dark blues. Aim for a hemline that falls right around the knee or slightly below, either in a straight pencil cut or a very restrained A-line. Tucking the blouse cleanly into the waistband gives the outfit its rigid, professional definition.
The Wellness Session Dress Option
If you prefer a single-piece build, the Vintage Burgundy Dress matches the subdued red she wears during Mark’s wellness checks. The garment features long sleeves, a modest neckline, and a structured bodice that feels vintage without looking like theatrical costume wear. The shade should lean deep wine or brick red rather than bright crimson to preserve the dim, clinical lighting aesthetic of the testing wing.
Styling the Hair and Makeup
Ms. Casey’s hair is one of her defining physical traits. The Black Wavy Bob Wig should hit right along the jawline or collarbone, featuring gentle, sculpted waves that stay firmly in place. Her hairstyle never appears messy or windblown; it has a controlled, glossy set reminiscent of late-sixties salon styling. A center or subtle off-center part with smoothed flyaways helps establish her unnervingly composed presence.
Her makeup remains minimal and porcelain-matte. A neutral foundation, softly groomed brows, and a muted, neutral rose lipstick match her quiet on-screen appearance. Heavy contouring or dramatic eyeliner would disrupt the clinical, detached presentation.
Footwear and Lumon Protocol
Finish either outfit with a pair of Grey Heels. Mid-height pumps or block heels in matte leather or suede fit the Lumon corporate standard seamlessly. Neutral grey harmonizes with both the tweed separates and the burgundy dress, giving you an understated foundation that feels authentic to the severed floor’s muted hallways.
