A NOTE FROM
SOPHIA & OLIVER
For over 25 years, this boutique was more than a business to me.
It was my second home.
Every collection, every display, and every customer who walked through our doors became part of a journey that shaped my life.
As the years passed, running the boutique became more difficult, and eventually I was faced with a decision I never thought I would have to make.
Closing the doors was heartbreaking.
I wasn’t just leaving behind a shop. I was saying goodbye to a place filled with memories, friendships, and years of hard work.
When I felt ready to let everything go, my son Oliver encouraged me not to.
He reminded me how much this boutique meant to me and to so many of our customers.
Together, we decided to bring the remaining collection online, giving these carefully chosen pieces a final home before this chapter comes to an end.
This Retirement Sale is more than a sale.
It’s our way of saying goodbye, thank you, and celebrating everything this boutique has meant over the years.
From the bottom of our hearts, thank you for being part of our story.
With love,
Sophia & Oliver
