Explore Hat Days of years past through photos

Hat Day is tomorrow, May 3.

And that means an afternoon of cocktails, fascinators and Project Runway's Tim Gunn at the Franklin Park Conservatory and Botanical Gardens. Proceeds from this fabulous day benefit educational, horticultural and community gardening programs at the Conservatory.

We looked through the past few years of Hat Day photos and put together a slideshow for you to browse. Enjoy!
