We are getting married outdoors in the biergarten at a local German restaurant. (Or indoors in the banquet hall if it rains.) There will be chairs during the ceremony but the seating for the reception will be picnic tables. I'm worried about people dressing up and having to climb in and out of picnic tables (mostly women in dresses and pantyhose). Should I include a note with the invitation to dress appropriately? Should I try to cover the benches of the table? Has anyone done that, I don't know how difficult it would be. Is this a silly thing to even worry about??
