We sent invites to one person per couple/family member. When you RSVP, you'll see your spouse/children/partner's name or a plus one to the invite.
Semi-Formal: Which for us means a cocktail dress for ladies, and a suit jacket isn't strictly necessary for men. Also preferably not black. The ceremony will be outside, so pointy high-heels are not recommended.
Children are added to the RSVP list, please check to see if they're invited.
There is now, but if you want to go for something different please feel welcome. Indoor plants would also be great.
