Kayali is the brainchild of Mona and Huda Kattan and was born from their love of perfume. The scents, which are inspired by Middle Eastern fragrance culture and the layering scents, were created by the sisters along with French perfume house, Firmenich. Our favourite scent in the range for summer? Kayali Déjà Vu White Flower (£67), which is loaded with white florals, patchouli, and Tahitian vanilla to make it beautifully warm and intoxicating. It also contains a 25 percent concentration of oil, meaning it's both powerful and long-lasting without being overwhelming.
