Emotion Index (EI) — Circumplex Positioning
Circumplex position governs all downstream HPEI decisions. Research basis: Mehrabian & Russell (1974); Eysenck (1941).
| EI Dimension | Look 01 — Red Cape Dress | Look 02 — Lime Croc Jacket |
|---|---|---|
| EI Position | Passion | Courage |
| Arousal Level | High Arousal | High Arousal |
| Pleasure Valence | High Pleasure | Pleasure-Tension |
| EI Position Code | High Arousal + High Pleasure Romantic Dominant register | High Arousal + Pleasure-Tension Sovereign / Rebel register |
| Circumplex Quadrant | Upper-right — Excitement zone (positive valence, high energy) | Upper-centre — Tension zone (positive with confrontation) |
| Primary Archetype | The Lover (Jung / Pearson) | The Hero / Rebel (Jung / Pearson) |
| Research Basis | Mehrabian & Russell (1974): red is highest-arousal positive-valence colour. Valentino scarlet confirms. | Eysenck (1941): unconventional colour combinations correlate with high Openness to Experience. |
EI Justification — Look 01
- Saturated red anchors the look in high-arousal, high-pleasure EI space.
- Cape silhouette increases volume without aggression — maintains Passion, avoids Pride.
- White brogues act as a pleasure amplifier — contrast without destabilisation.
EI Justification — Look 02
- Acid lime introduces controlled disruption within high-arousal EI.
- Formal black tailoring stabilises the system — prevents collapse into chaos.
- Result: Pleasure–Tension state with confrontation, not harmony.
PEG Filter — Positive Emotion Granularity
Vague intent → named emotion from the 25-typology. One primary, one secondary maximum. All downstream decisions evaluated against these.
| Consumer Purpose | "Walk into that room and be the one they all turn to look at — not because I demanded it, but because I earned it." | "I am impossible to ignore and I know it. Every room I enter, I've already won before I speak." |
| 25-Typology Cluster | Aspiration cluster — Passion / Desire Secondary: Vitality — Empowerment | Assurance cluster — Pride / Confidence Secondary: Vitality — Courage |
| Primary Emotion | PASSION | PRIDE |
| Secondary Emotion | Empowerment | Courage |
PEG Translation — Look 01: Red Cape Dress
| Vague brief | PEG-refined emotion | Resulting design decision |
|---|---|---|
| "Make it feel powerful" | Passion (Aspiration) | Saturated red, volume cape, mini length — sensuality over authority. Red signals desire, not dominance. |
| "Make it feel feminine" | Desire (Aspiration) | Body-conscious skirt beneath cape. Deep colour. Feminine shape over defined waist. |
| "Make it feel free" | Empowerment (Vitality) | White oxford brogues — unexpected pragmatic disruption. Pleasure without constraint or apology. |
PEG Translation — Look 02: Lime Croc Jacket
| Vague brief | PEG-refined emotion | Resulting design decision |
|---|---|---|
| "Make it feel bold" | Pride (Assurance) | Acid lime in full saturation — chromatic confidence requiring no apology or explanation. |
| "Make it feel street" | Courage (Vitality) | Croc emboss on bomber silhouette — status texture without institutional signalling. |
| "Make it feel exclusive" | Fascination (Assurance) | Logo belt + clear novelty pouch — legible status accessories that reward close reading. |
P²VP Consumer Persona — Personality × Purpose × Value × Product
Target persona identified before design. All HPEI decisions evaluated against it. Archetype basis: Mark & Pearson (2001).
| P²VP Dimension | Look 01 — Romantic Dominant | Look 02 — Sovereign Rebel |
|---|---|---|
| Archetype | The Lover · High Arousal + High Pleasure | The Hero / Rebel · High Arousal + Pleasure-Tension |
| Personality | High sensory intensity. Requires visual dominance. Rejects minimal restraint. | Murray n-Exh dominant. Very high Openness. Violates conventional taste codes. |
| Purpose | Immediate recognition. Emotional centrepiece. Garment introduces before speaking. | Cultural declaration. Positioned above trend — authors trend. |
| Value | Authenticity of desire. Anti-beige. Colour as courage. | Originality over consensus. Status must be legible and confrontational. |
| Product Outcome | Saturated red → Passion register. Cape volume → visual amplification. Mini length → intimacy, not authority. White shoe → disruption accent. | Acid lime → Courage register. Croc emboss → status texture. Oversized bomber → visual dominance. Black trouser → discipline frame. |

HPEI Dimension Specification — Visual · Tactual · Multi-Sensory · Audio
Named emotion overrides aesthetic preference. Each dimension specified against the EI position.
| Dimension | Look 01 — Red Cape Dress | Look 02 — Lime Croc Jacket |
|---|---|---|
| Visual Colour | Saturated scarlet. B ~65%, S ~90%. Monochromatic. Matte finish — Passion register, not Desire. | Acid lime. B ~70%, S ~95%. Maximum saturation outside luxury grammar. Forces attention — non-optional visibility. |
| Visual Silhouette | Structured cape over body-conscious mini. Volume at upper body, sensuality below. No print — monochromatic restraint amplifies colour. | Oversized bomber over tailored wide-leg. Jacket maximalism vs trouser discipline. Croc emboss: heritage subverted by extreme colour. |
| Tactual Fabric & Hand-feel | Structured textured woven, medium-heavy. Cape holds sculptural integrity. Matte surface. At touch: weight = investment = Trust. | Embossed leather / high-quality PU, stiff, semi-gloss. Croc catches light directionally. At touch: weight + rigidity = armour. |
| Tactual Embellishment | None. Colour and silhouette are the spectacle. White brogues as sole disruption accent. | Metal hardware: logo belt, gold/brass. Clear novelty pouch. Legible status markers at close range. |
| Multi-Sensory Fit & Movement | Body-conscious base. Cape motion → amplification per step. Theatrical presence at distance. | Single-unit movement. Standing = volume statement. Walking = procession. Trousers = discipline frame. |
| Audio Signature | Soft swish of structured fabric. White oxfords: quiet sole. Controlled spectacle — arrival without aggression. | Hardware clink at movement. Leather stiffness — no fabric rustle. Presence is visual, not sonic. |
Thick Idea — Emotional Architecture & Sequence
Emotion sequence: first visual contact → tactual engagement → wearing verdict.
Look 01 — Emotion Sequence: Red Cape Dress
| First contact (visual at distance) | Point of touch (tactual) | Wearing verdict (multi-sensory) |
|---|---|---|
| Desire. Scarlet registers before silhouette. Involuntary attention capture. | Trust. Weight + texture → investment signal. Pre-wear confidence. | Empowerment. Cape motion → amplification. Elevated posture. |
| Q2 — Visual carriers | Scarlet → Passion. Cape → Empowerment. Zero print → restraint. White shoe → disruption signal. |
| Q3 — Tactual carriers | Medium-heavy woven → Investment. Matte → Passion. Weight in hand → Trust. |
| Q4 — Wearing experience | Cape motion → per-step amplification. Body-conscious base → sensuality + spectacle. |
| Q5 — Deep concern | Fear of disappearing. Addresses need for visual impact without aggression. |
Look 02 — Emotion Sequence: Lime Croc Jacket
| First contact (visual at distance) | Point of touch (tactual) | Wearing verdict (multi-sensory) |
|---|---|---|
| Fascination. Acid lime → colour grammar violation. Involuntary double-take. | Desire. Croc depth + leather weight → sensory richness. Investment legible at close range. | Pride. Armoured. Deliberate. Declared. Room recalibrates. |
| Q2 — Visual carriers | Acid lime → Courage. Croc emboss → Fascination. Oversized → Pride. Black trousers → discipline frame. |
| Q3 — Tactual carriers | Embossed leather → Authority. Semi-gloss → Reflective pride. Metal hardware → Rebellion + Luxury. |
| Q4 — Wearing experience | Standing → volume statement. Walking → procession. Trousers confirm discipline retained. |
