Specific Opportunity Details
Every year deserves a signature ending. This December, join us for THE 2025 finalé for women in their thirties.
The Signature Soirée returns for our End of Year Edition – a day created to mark the year just gone and set the frequency for the one ahead.
An afternoon that unfolds in layers: an à la carte brunch, champagne, conversations worth having, unexpected live moments, a female DJ, luxury gift bags and immersive brand activations across one of Mayfair’s most exclusive spaces – Mistress of Mayfair.
It’s not about how 2025 looked on paper. It’s about marking it. Owning it. Ending it in the room you want to be in, and stepping into 2026 excited and ready for whatever is yours next – seen, certain, unforgettable.

Other Info
On 14th December we return to Mayfair for our flagship UK event: the HT Signature Soirée. Our last London event sold out with 150+ women, seven speakers, and was featured in Cosmopolitan as the #1 go-to event for women in their 30s. This year we’re scaling bigger – 150+ intentional buyers, London’s most in-demand event, and an atmosphere rooted in confidence, celebration, and connection.
We’d love your brand to join us as headline sponsor. Beyond visibility across all event moments, your brand would have the option to take over a beautifully curated red velvet corner – positioned as a “celebrate yourself” space, showcasing your Winter/Christmas collection. Guests could shop key pieces at an exclusive rate, making your brand the brand they leave with and remember.
There’s also potential to explore a Her Thirties x your brand edit — rooted in our event colour palette of red, black, gold and burgundy – tying the collection directly into the evening’s aesthetic and amplifying the “turnaround” feel. Plus the team wearing pieces of the collection for the event.
This isn’t just partnership, it’s cultural alignment. A moment to root your brand directly in the lives of thirties women – confident, aspirational, and ready to invest in fashion that lasts.
