Founder's Story

When we started Maximo Mayfair, it was born from a deep love for classic British style — timeless menswear, crafted with purpose and pride. What began as a shared passion between the two of us grew into something much more: a brand that found its way into the wardrobes and lives of so many loyal customers.

For years, we’ve poured our hearts into designing collections that balance elegance, comfort and character. We’re endlessly grateful to those of you who believed in what we were building and supported us along the way.

But the fashion world has changed. Competing against large corporations with limitless budgets has made it harder than ever for small, independent brands like ours to continue. Despite our passion and persistence, we’ve had to accept that carrying on is no longer sustainable.

As partners in business, and in life, we’ve made this difficult decision together. It’s time to step back, focus on our family, and begin a new chapter.

To mark the end of this journey, we’re holding a major clearance sale -everything must go. This is the final opportunity to take home a piece of Maximo Mayfair before it disappears for good.

While this may be goodbye for now, the values we started with - quality, elegance, and timeless style - will always remain at the heart of what we created.

With gratitude,

Emma & Charles
