On Hat Day, all other accessories take a backseat.
Hundreds of women will gather Friday at the Franklin Park Conservatory for the 10th annual Les Chapeaux dans le Jardin. The event, which includes a luncheon, fashion show and live auction, has raised more than $1.6 million to benefit the Conservatory's education outreach programs.
