Echika Hieda is a prodigy Electronic Crimes Investigator in Your Forma who dives into the memories of crime victims, partnered with the android Harold on her cases. That investigator identity, and her partnership with Harold, is what makes this costume specific to Your Forma rather than a generic detective look. The series began as a Dengeki Bunko novel by Mareho Kikuishi and reached anime in 2025, with Echika's investigation work at the center of the story. This set recreates the field uniform she wears on the job as the Echika Hieda Full Set, split into its individual pieces rather than one single garment.
Eight Pieces That Build Echika's Field Uniform
The Echika Hieda Full Set is made up of a tunic, shorts, a capelet, a waist band, a harness, a leather belt, a pouch and a thigh strap, eight pieces split between the base clothing and the strapped accessories. It's built as an adult costume rather than a kids' cut, and it works for Halloween or any convention outing.
- Tunic and shorts make up the base clothing.
- Capelet and waist band are the additional clothing pieces.
- Harness, leather belt, pouch and thigh strap are the strapped accessories in the set.
Fabric Behind the Tunic and the Leather Pieces
This set combines a uniform fabric with faux leather. That mix of plain clothing and gear-like strapping fits the practical, on-duty appearance Echika has in Your Forma. Together, the uniform fabric and faux leather pieces make up all eight components of the Echika Hieda Full Set.
Finishing Echika's Short Black Bob
Echika wears a short black bob, so a wig cut the same way is the fastest route to the look. Black tights and knee boots pair well with it, matching her own styling, and they're worth lining up before the wig since both are easy to find in plain black. None of the wig, tights or shoes ship with the Echika Hieda Full Set. Since Echika's hair is specifically a short black bob rather than a longer style, a longer wig would work against the resemblance.
Every Angle of the Echika Hieda Full Set
Beyond the front view used above, the listing for this costume adds angle, back, detail and pieces photos of the Echika Hieda Full Set. The detail shot gives a closer look at the harness and leather belt. The pieces photo in particular lays out all eight components separately, which is useful for checking everything arrived before you start dressing. Between the front, angle, back, detail and pieces photos, the full set is visible from every side without needing to guess at what's included. With five photos covering the full set, it's easier to see all eight pieces before deciding which size to order.
Picking a Size for the Full Set
The Echika Hieda Full Set currently comes in one style, offered in sizes S, M, L, XL and XXL, with no second version to compare it against. Because it ships as a single style rather than multiple cuts, the size you choose applies across the tunic, shorts, capelet, waist band, harness, leather belt, pouch and thigh strap at once. Pair whatever size you choose with the wig, tights and boots from the styling notes above, since those come from elsewhere and aren't tied to the costume's own sizing.
