With the UK experiencing its hottest May day on record, reaching 34.5°C, etiquette expert Laura Windsor has shared a comprehensive guide on how to navigate social situations during heatwaves. Windsor emphasizes that wearing a bikini in parks is inappropriate, while men should opt for tailored shorts when in the city. She advises against setting up elaborate picnics in public spaces, suggesting that gatherings should consist of light snacks and drinks, and highlights the importance of bringing something for the host. Windsor also cautions against discussing the heatwave or complaining about the weather, advocating for a 'stiff upper lip' approach. Personal grooming is crucial; she recommends wearing deodorant, avoiding heavy makeup, and ensuring feet are presentable. Additionally, Windsor stresses the need for sunscreen and proper attire, suggesting that a top should be worn unless on the beach. Her guidelines aim to help individuals maintain dignity and respect for others during the sweltering summer months.
