Size Guide How To Measure

Finding the right size is important for the best fit.

Important Size Notice 

Our costumes are based on Asian sizing, which generally runs smaller than US/EU/UK sizes.

Please DO NOT select your size based on your usual size. Always refer to the garment measurements provided on each product page.

If you are between sizes, we recommend choosing the larger size for comfort and easier alteration.

If you are unsure about sizing, feel free to contact us before ordering with your height, weight, chest (bust), waist, and shoulder measurements.

Size Chart

All measurements are garment measurements (not body measurements).

Please compare the measurements with your own clothing for the best fit.

All measurements are in cm and inches.

Unit conversion: 1 cm = 0.39 inch | 1 inch = 2.54 cm

All measurements are manually taken from the actual garment. A tolerance of 1–3 cm ( 0.39-1.18 in ) may occur. Different manufacturers may use different cutting standards. Please always refer to the size chart listed on the individual product page before ordering. For items with elastic waistbands: The elastic waistband provides a flexible fit and allows additional stretch for comfort. For the best comfort, your body waist measurement should be smaller than the listed maximum stretch measurement. Color may vary slightly due to lighting and monitor settings.

How to Measure

We recommend having someone assist you when taking measurements for better accuracy.

Measure around the fullest part of your chest/bust. For female customers: Please wear a bra when taking this measurement. 

Waist: 
Measure around the smallest part of your natural waistline, which is where your trousers normally sit. Keep one finger between the measuring tape and your body for comfort.

Rui Cosplay Costume

 – Featuring a subtle woven texture haori

This Rui cosplay costume is inspired by his iconic spider demon appearance in Demon Slayer: Kimetsu no Yaiba, combining eerie aesthetics with refined detail. 

The outfit features a subtle hidden pattern design that enhances the spider-themed visual effect, especially under different lighting conditions. Crafted from high-quality materials, the costume offers both comfort and durability while maintaining an accurate anime silhouette. Perfect for conventions, photoshoots, and dark-themed cosplay content, this Rui cosplay costume allows you to fully embody the unsettling charm of the character.

Character Inspiration:

Rui is one of the most memorable antagonists in Demon Slayer: Kimetsu no Yaiba. As Lower Moon Five of the Twelve Kizuki, Rui is known for his chilling calmness and obsession with the concept of “family.” His spider-like abilities and pale, haunting appearance make him a uniquely eerie presence in the series. Despite his villainous role, Rui’s tragic backstory adds emotional depth, making him a fan-favorite among Demon Slayer antagonists.

  • Subtle woven texture of the haori fabric that enhances the depth and authenticity of the anime design
  • Screen-accurate Rui cosplay costume design inspired by Demon Slayer
  • Comfortable and breathable fabric suitable for long convention wear and cosplay photoshoots
  • Complete Rui Cosplay outfit set, including a White kimono and a Red obi belt
  • Ideal for anime conventions, cosplay events, Halloween, and anime photography

Made from premium uniform cloth, this Rui cosplay costume is designed to hold its shape and withstand multiple wears. The Haori features a subtle jacquard pattern, giving the fabric a refined texture that looks high-end and professional under any lighting, without feeling thin or flimsy.

Unlike many standard versions on the market that use flat printed fabric, our Rui cosplay costume incorporates a woven jacquard texture directly into the haori. This creates a layered and realistic visual effect, especially in photos or under convention lighting.

The subtle woven pattern adds depth and dimension to the haori, bringing it closer to the anime’s appearance. For cosplayers who value authenticity and detail, this textured haori design offers a polished and premium look while remaining comfortable for long wear at conventions, photoshoots, or anime events.

  • White kimono
  • Red obi belt
