Marc Jacobs president Robert Duffy is set to tie the knot with boyfriend Alex Cespedes next Tuesday in Provincetown, Massachusetts, WWD reports.

"We have been living our life together and sort of making steps towards this. But it really didn't become like a thing that I would do [until recently]," Duffy said. "It just never entered my mind."

Duffy added:

"I've always fought for equal rights for gay people. I've always done fund-raisers, and I've always been out there politically for it....In the state of Massachusetts I can have the same rights as everybody else. I've always had a house there. I spent summers there as a kid, and I always considered Massachusetts sort of like my home. All of a sudden, everything started making sense to me. And I knew it was something really important to Alex."

Jacobs will be Duffy's best man and they'll be clad in the designer's suits. The wedding will be a small affair, with a guest list of 86 people.
