Coty, 30, is an attorney. Matt, 31, is a physical therapist. They live in Logan Circle.

The Main Event: They’ll have an outdoor ceremony April 29 overlooking the Chesapeake Bay Bridge. For their honeymoon, they’re visiting Bequia and Mustique in the Caribbean — the latter island being a favorite haunt of royals Will and Kate.

How They Met: In college.

First Date: A sorority function Coty invited him to. She handcuffed him to her for the night — literally.

How He Proposed: New Year’s Eve, after a private plane ride with wine and chocolate.

Pet Names: They call each other “goat.” He also calls her “sweet pea.”

When They Knew: “When I saw him taking care of my Yorkies like they were his own.” “When she took me to a brewery even though she hates beer.”

Making It Unique: A friend (and first-time officiant) will perform the ceremony.
