As a humble participant of corporate America, I set out to design a Halloween costume that conveyed “A Member of the Rat Race.” The concept combined everyday professional attire with a custom-designed rat mask to create a recognizable visual pun.

The challenge was translating a conceptual idea into a functional, wearable product using materials and techniques I had never worked with before. The design needed to balance several competing constraints: maintaining the recognizable symbolism of a rat, ensuring the mask was structurally stable and comfortable to wear, and preserving my ability to enjoy the party.

From a design perspective, the challenge became an exercise in technique research, material experimentation, and iterative refinement to transform an abstract idea into a cohesive physical artifact.

I began by defining the core concept and North Star for the design: the costume should immediately communicate rat

To refine the visual language, I conducted exploratory research into:

• Mask-building techniques from around the word, such as cardboard sculpting and structural mesh frameworks

• Clay layering methods used in theatrical and costume design

• Visual references, including interpretations of the Rat King from "The Nutcracker", to establish tone, silhouette, and expression



Using these references, I created multi-angle sketches to map proportions and define the mask’s structure and personality.

I then built an initial "wire frame" using lightweight materials to form a structural base that could fit securely over my head. This stage focused on establishing the mask’s overall shape, internal support system, and wearability.



The design evolved through multiple iterative cycles:

1. Cardboard and masking tape to establish the general shape

2. Wireframe adjustments to refine structure and stability

3. Papier-mâché reinforcement to strengthen the form and reveal surface imperfections

4. Air-dry clay sculpting to develop detailed facial features and textures

5. Sanding and painting to enhance expression and create a cohesive final aesthetic

Throughout the process, I repeatedly revisited the original concept to ensure the design maintained its intended reaction while still remaining functional as a wearable object.

The final mask was successfully recognized by many a party-goer.

While the project was created for the joy of creation and to have a enviable Halloween costume, it reinforced several design principles that translate directly to professional UX and product work by:

• establishing a clear north star to guide design decisions

• grounding creative execution in research and references

• using rapid prototyping and iteration to refine ideas

• balancing concept, usability, and execution

Working through unfamiliar materials also required structured experimentation and continuous recalibration, mirroring how complex product and design initiatives evolve over time.

Ultimately, the project highlighted the value of process-driven design, iterative problem solving, and aligning the final outcome with the original intent of the concept.
