Help with wedding attire for a camping wedding.

Hi all! I am attending a wedding in September at a farmhouse in Vermont. There isn't much information on the invitation, but the gist is that we are camping on the lawn at the farmhouse after the reception.The invitation does not include what type of attire the guests should wear, although I am assuming it is informal and more casual. What type of dress/style would you recommend I wear as a guest? Do you think a cocktail dress would suffice? I just don't want to be under/over dressed.In addition, does anyone have any experience with camping after a wedding? Thank you! via /r/weddingplanning http://ift.tt/2uP7fj3
