Our Story
At Kate & Simon London, everything began with a shared love for fashion, creativity, and timeless style. Kate and Simon first met during their student years while studying Fashion Design & Business.
Simon grew up in the Netherlands, while Kate was raised in the United Kingdom. Despite their different backgrounds, they quickly connected through a mutual appreciation for elegant fashion, travel, and modern European living.
What started as a friendship slowly grew into a life built together. After years of travelling between London and the Netherlands, they decided to create a brand that reflected their own vision of women’s fashion effortless, refined, and made to be worn every day.
Today, more than 12 years later, with two wonderful children and years of experience within the fashion industry, Kate & Simon London has become a natural extension of who they are and what they believe in.
Inspired by the understated elegance of London style and the relaxed simplicity of modern European fashion, every collection is carefully curated with attention to quality, comfort, flattering fits, and timeless silhouettes.
For Kate and Simon, fashion is not about following every trend. It is about creating pieces that feel beautiful, comfortable, and easy to wear pieces that naturally become part of your everyday life.
Their goal has always remained simple: helping women feel confident, feminine, and comfortable in their own style.
