Got this for my mum's birthday and she wore it the same day. Feels way more expensive than what she paid.

Already own two other pieces from Madison May's Boutique and this one might be my favorite place to shop. Solid stitching, no loose threads.

Customer review

Our final sale ❤️

For over 20 years, we’ve built Madison May Boutique in Palm Beach together as a family, pouring our hearts into every collection and every piece we chose. We’re incredibly grateful for every customer who has supported us along the way.

But after more than two wonderful decades, the time has come for us to say goodbye.

My husband’s health has become our priority, and after many difficult conversations, we’ve made the heartbreaking decision to retire and close Madison May Boutique. It’s not how we imagined our journey would end, but right now, being together and focusing on his health matters more than anything else.

That’s why we’re holding our Retirement Sale. Our remaining collection must be sold before we close our doors for the final time.

This is your final opportunity to shop Madison May Boutique. Once these pieces are gone, they will not be restocked.

Every order helps us close this chapter with a little more peace and means more to our family than you may ever know.

From our family to yours, thank you for being part of the Madison May Boutique story for the past 20 years. ❤️
