Much like the wedding theme probably isn’t “wedding,” the shower theme should be something fun and inspired by the bride. Does she love cats? Great! Cat-themed shower it is. Does she love a good royal wedding? Have everyone come in hats and fascinators. Just don’t go overboard with the theme — it might be weird to have a bunch of stray cats running around. Having a theme will also make it a lot easier to land on the right venue, too.
