Rubies DC Super Hero Girls Harley Quinn Costume
This is the DC Super Hero Girls version of Harley Quinn based on the animated series. The set includes a top, shorts with attached leggings, an eye mask, a wristband, a belt, and red and blue hair pieces. The manufacturer uses 100% polyester and lists this for girls in size small (4-6). Reviewers report this costume runs small compared with standard clothing sizes. Use the Rubies size chart before ordering. Contains small parts, not suitable for children under 3 years.
Reviewers note the top has no stretch and can feel stiff or scratchy against skin. Several suggest putting a thin tank top underneath for comfort.
Best For: Girls who want the bright DC Super Hero Girls version of Harley Quinn in a top-and-shorts style rather than a jumpsuit.
Rubies DC Super Hero Girls Harley Quinn Jumpsuit
This is the DC Super Hero Girls Harley Quinn costume in a jumpsuit format. The set includes the jumpsuit, a headpiece, and an eye mask. The manufacturer notes this is officially licensed and recommends using the Rubies size chart rather than choosing based on age or clothing size.
The jumpsuit format is the main difference from the separates version above. It is a single piece rather than a top and shorts combination, which changes how it looks and how it goes on. Check the size chart carefully before ordering.
Best For: Girls who want the DC Super Hero Girls Harley Quinn look in a one-piece jumpsuit rather than separate top and shorts.
Rubies DC Comics Villains Harley Quinn Costume
This is the DC Villains version of Harley Quinn. The set includes a black top with white star print and a “PUDDIN” hem band, a red satin jacket with an embroidered diamond logo, shorts, a belt, and leggings. The manufacturer lists this as officially licensed and sizes it at girls small (6/7). Reviewers also report that this costume runs small compared with standard clothing sizes.
The red satin jacket is the defining visual difference here. It gives this costume a different villain-style look from the animated Super Hero Girls versions above.
Best For: Girls who want the red-jacket Harley Quinn villain look rather than the animated series style.
Rubies DC Super Villains Harley Quinn Tween Costume
This is the tween-sized Harley Quinn costume. The set includes a headpiece, eye mask, dress, glovelettes, and printed tights. The manufacturer sizes this at tween small (bust 27 inches, waist 24 inches) and notes it is officially licensed by DC. Dry clean only.
Reviewers flag two consistent sizing issues: the tights tend to run very small while the glovelettes run large. Several recommend replacing the tights with standard leggings. Others describe the dress as working best on a smaller or more petite frame and note that it can run short on taller kids.
Best For: Older girls who want a Harley Quinn dress costume and are willing to check the garment measurements carefully before ordering.
DC Comics Harley Quinn Union Suit Pajama
This is a Harley Quinn union suit in a pajama design. The one-piece features a full zip closure up to the neck and a hood with 3D jester ears. The manufacturer makes it from soft poly microfleece and lists sizes from 7-8 through 18-20. It is machine washable and officially licensed by DC Comics, with the classic red-and-black diamond design.
The union suit is the only option in this list designed for use as both pajamas and a costume. Reviewers commonly describe it as comfortable, and some report that it washes well.
Best For: Girls who want a Harley Quinn costume they can wear on Halloween and continue using as pajamas afterward.
Frequently Asked Questions
Which Harley Quinn looks are included in this list?
The separates costume and the jumpsuit are based on the DC Super Hero Girls animated series. The DC Villains costume and the tween dress use red-and-black Harley Quinn villain styling. The union suit uses the familiar red-and-black diamond design in a pajama format.
Why do so many reviewers say the sizing runs small?
All four Rubies costumes in this list are reported by reviewers as running smaller than standard clothing sizes. Rubies recommends using their own size chart rather than choosing by age or clothing size. If your child is between sizes, compare their measurements with the Rubies chart and pay particular attention to reviewer comments about fit before choosing.
Are any of these suitable for a school Halloween event?
None of the five costumes use a full-face mask. The eye masks included with some sets are partial and leave most of the face visible. Check your school’s specific rules on masks and accessories before buying.
Can these be worn over warm clothes on a cold Halloween night?
If you expect cold weather, check the costume measurements before ordering with layering in mind. The Super Hero Girls separates may offer more flexibility for adding a thin layer underneath than some one-piece designs. For the union suit or fitted costumes, make sure there is enough room before planning to add clothing underneath.
