Over 7,500 women found their confidence in Sophie’s designs — from their daughter’s graduation to their own golden anniversary

For 48 years, I’ve poured my heart into two little ateliers in New York — one tucked away on Madison Avenue, the other nestled in SoHo on Prince Street.

From sketch to final stitch, I handcrafted every piece to honor timeless beauty, individuality, and grace. I never followed trends. I followed women — their stories, their lives, their quiet strength.

Every dress, every bag, every pair of sandals that left my hands was meant to last.

Now, as I prepare to close both ateliers and step into retirement, I offer you this final collection.

These are the last pieces I will ever make.

— Sophie

My Personal Promise

After nearly five decades of dressing women I admire, I want you to feel nothing less than wonderful in anything you choose from my collection.

If your piece doesn’t feel perfect — in fit, in feel, or in spirit — I welcome you to return it within 30 days. No stress. No hard feelings.

This collection is my goodbye — but my promise to you stays forever.

— Sophie

Every garment I design is crafted with love and meticulous attention to detail. I handpick the finest silks and fabrics, and personally oversee every step of the creation process in my Madison Avenue atelier.

My goal is to create clothing that not only makes you feel extraordinary but also becomes a timeless part of your wardrobe for years to come.

Fine fabrics are like treasures that become more beautiful with proper care. To keep your garments looking their best, I recommend following the care labels carefully and storing them on padded hangers in a cool, dry place. For delicate silks, consider professional dry cleaning to preserve their luxurious feel. If you ever have any questions about caring for your pieces, just let me know—I'm always here to help.
