Wedding arch

The Wedding Arch was introduced in The Sims 2. While Sims can get married or enter a Joined Union without using the arch, it allows a player to add a bit of formality, as Sims who get married or joined under the arch will change into their formal clothes. If the relationship between the two Sims is too low, one may call off the wedding. While this can happen whether or not the arch is used, it's more dramatic if the arch is involved. Players who have The Sims 2: Celebration Stuff will be able to choose from two different arches.

Using the wedding arch to be married will begin a cinematic. If successful, the sims will exchange vows and rings, then flower petals will fall, and the sims will kiss. If unsucessful, the sim who did not initiate the interaction will watch the other sim about to put on the ring, then after a few tense moment will jerk back hand and run away from the wedding arch. The camera focuses on the rejected sim as you hear running, a car door slamming, and tires screeching as the sim escapes. (An unsucessful marriage will definitely ruin the party.)
