My Daughter outside our Store
IMPORTANT NOTICE

WE REFUND EVERY 10TH ORDER

With excitement, and a heart full of gratitude, I can share that today is my daughter Maeve's 23rd birthday. She's the one who stepped up and helped me build Sienna & Maeve after her father and I divorced, and there's no one I'd rather celebrate with than you — the women who've been with us all along.

As a thank you for your loyalty over the years, we are offering our handcrafted pieces at up to 80% off during today's Birthday Sale. In addition, we will refund the full purchase amount of every 10th order placed. Secure a piece of Sienna & Maeve's collection before today ends.

Founder & Designer

They can steal your recipe but the sauce won't taste the same.

Mass production can imitate a silhouette, but it can never replace the soul of a garment. Our secret ingredient is the human hand — every stitch is guided with care, precision, and intent. Each design is strictly limited to just 10 pieces. Because anyone can produce a dress, but the feeling of true rarity cannot be manufactured.
