For an Arkham Asylum Harley Quinn costume, start with her nurse-inspired game outfit rather than a general Harley Quinn shopping list. The white clothing, fitted red waist layer, blonde pigtails and dark accessories establish a different look from her jester suit or Suicide Squad outfits.

Match the game before buying pieces
DC explicitly identifies Harley’s Arkham Asylum appearance as a nurse costume. Use a clear image from that game to check the silhouette and details. Product titles sometimes combine “Asylum,” “City” and other versions, so the name alone is not a reliable match.
Pink-and-blue hair pieces and movie-branded jackets belong to different interpretations. You can mix versions deliberately, but they are not required pieces for this particular outfit.
Arkham Asylum costume checklist
- A white short-sleeved clothing base and skirt, or a matching nurse-style costume base.
- A red corset-style waist layer, fitted for comfortable movement.
- Blonde pigtails or a suitable wig and a small character-matched headpiece.
- A black eye mask, with clear eye openings.
- Dark hosiery, boots and wrist details selected against the same reference.
Assemble a practical interpretation
- Start with the white layers. Check coverage and comfort while standing, sitting and bending. Choose a length and fit that work for you rather than relying on the pose in a product photograph.
- Add the waist layer. A fashion vest or comfortably fitted costume corset can suggest the shape. Fit it over the actual clothing you will wear, without tightening it to force a smaller size.
- Arrange the hair. Test pigtails or the wig before attaching the headpiece. Make sure the combination remains stable when you turn your head.
- Fit the mask and accessories. Check that the eye openings stay aligned and that wrist pieces do not interfere with your hands.
- Choose footwear last. Try boots with the hosiery and complete outfit, then walk in them before the event.
A checked hosiery option
The Leg Avenue black fishnet thigh-highs on Amazon are an optional separate, not a complete Harley Quinn costume. The checked listing was a “One Size” selection and recommends garter support. Consult its size guide and decide whether thigh-highs or full tights are more practical for your outfit. We have not worn or tested them.
The ready-made nurse-style set previously linked here was unavailable when checked, so it is no longer presented as a current buying recommendation. If you find another complete set, compare the actual photographs and included-pieces list. Boots, wig, hosiery and props may be sold separately even when shown on the model.
Props and finishing touches
A handheld prop is optional. Check your event’s rules before selecting one, and plan how you will carry it when using your phone or taking a break. You do not need multiple weapons, necklaces, bags and collectibles to make the costume recognizable. Spend time on the base silhouette and fit first.
