The wedding is in January. In Colorado. Outside unless it's snowing too much. Where do I tell guests to bring their jackets? It could be beautiful and 55 or beautiful and 20. Do I put it on the invitation? That feels out of place. The RSVP card? I have already put it on the website, but not everyone will go to the website. Should I be amazingly awesome and call everyone the week before to remind them/give them a heads up? Do I not bother with it and hope they are smart enough to wear a jacket?
