A trim assembly includes a first trim member and a second trim member, each including an aesthetically-pleasing surface and a substrate-facing surface. A plurality of circumferentially-arranged projections extends axially away from substrate-facing surface of the first trim member. The second trim member includes an aesthetically-pleasing surface and a substrate-facing surface. A circumferential projection extends axially away from substrate-facing surface of the second trim member. The circumferential projection includes an axially-extending portion and a radially-extending portion. The radially-extending portion extends radially outwardly away from the axially-extending portion. The radially-extending portion forms a plurality of circumferentially-arranged passages configured for receiving the plurality of circumferentially-arranged projections for joining the first trim member to the second trim member when the plurality of circumferentially-arranged projections are at least partially disposed within the plurality of circumferentially-arranged passages. A trimmed assembly is also disclosed. A method for forming a trimmed assembly is also disclosed.
