We love your kids - we really do! But we want our wedding to be your night off! So we do ask that unless your invitation says "and family" that you make childcare arrangements.
If your invitation says "and Guest," then yes, if not, we would prefer if it was just you.
We're probably breaking some rules but..."Creative Formal" (a step down from "Creative Black Tie"). It's formal with some flair. Add some fun or vintage accessories, wear that dress that you've had no where to wear it to, bring out those velvet suit coats!
