The dressing register stays Andalucía-conservative-yet-decorative: cotton everything in summer-light cuts (cream, ivory, sand, traditional flamenco red + black + polka-dot), Lina (Sevilla 1960), Pol Núñez, Aurora Gaviño, Atelier Flamenco Sevilla. The Cathedral of Seville + Real Alcázar enforce strict modesto. Real Maestranza bullring at peak summer (June bullfights every Sunday 18:30 + Sundays through Holy Week + Feria + October).
