Honkai: Star Rail lets players choose Stelle or Caelus as the Trailblazer, and this product page mirrors that choice. Both wear a dark open jacket with yellow trim, but the lower half splits: skirt for Stelle, trousers for Caelus. The Honkai Star Rail Trailblazer Stelle And Caelus Cosplay Costume With Wigs sells each full outfit and each grey wig as its own style, so you cast first and measure second.
Four styles on the page
- Stelle Full Outfit and Caelus Full Outfit: complete costume sets as pictured, Adult XS–XXXL, polyester with faux-leather details.
- Stelle Wig and Caelus Wig: grey wigs, One Size with adjustable caps.
Order the matching wig unless you already have grey hair that photographs well. Do not mix Stelle’s skirt option with Caelus’s pants in your head and then click the wrong full outfit—the styles are sold as complete character sets. Mixing pieces across styles is how people end up with a jacket that fits and a lower half that does not.
Stelle’s coat, skirt and top
Stelle coat length runs 72–81, bust 84–88 to 108–112, waist 70–74 to 94–98. Skirt waist is tighter at 56–60 to 80–84, with hip 82–86 to 106–110 and length 38–44. Top bust sits 82–86 to 106–110. Size primarily by coat bust and skirt waist. The skirt waist is smaller than the coat waist because they sit on different layers. If your waist sits at the top of a skirt range, size up so you can sit on convention floors without fighting the zipper.
Caelus’s coat, pants and top
Caelus coat is longer, 97–109, with bust 94–98 to 118–122 and shoulder 41–47. Pants waist 70–74 to 94–98, hip 90–94 to 114–118, length 94–106. Top bust 92–96 to 116–120. Size by coat bust and pants waist together. Height bands for both characters run 146–152 at XS to 184–190 at XXXL. Between sizes, take the larger. Hand measurements can be off by 1–3 cm.
Yellow trim, wigs and Express photos
The yellow lining is the recognition flash in crowded halls. Keep the jacket open enough to show it. Brush grey bangs slightly forward. Undershirts in black or white help if the open jacket gapes while you move. Check the faux-leather trim for shipping creases and warm them gently with a steamer.
Double-check the style name in your cart against the size chart you used, and keep a photo of the chart on your phone for reference at the event.
Before the event, put the full set on once at home: walk, sit, climb a few stairs and raise your arms. Fix straps, belts and hems now rather than discovering them in a venue bathroom with no mirror space.
For Astral Express group shots, stand Stelle and Caelus a half-step apart so both yellow linings read without overlapping. If you only buy one wig, match it to the outfit you ordered—the cuts are not identical in the reference art. Carry two bobby pins for bangs that fall into your eyes during panels. Game conventions and Halloween suit this set. Cast the character, open that character’s charts, then add the matching wig.
