Meghan Linsey and Tyler Cain Elope in Hawaii!

Linsey wore a custom Olia Zavozina gown, which was designed two years ago after the couple first got engaged. Getting the right fit, she tells PEOPLE, was "really important" to her. "I wanted something that would hug my curves but still look elegant," the singer-songwriter said. "The beading and button details on the back are beautiful and the train is miles long, which I love. Olia is the sweetest human and so insanely talented. She made my dress two years ago and has held on to it all this time!"
