Thanks for bringing this up. I'm headed to an outdoor wedding for a friend I am not out to. Do you guys think slacks and a dress shirt without a tie would be formal enough?
Depends on the variety of "outdoor." I must now amend my earlier comment saying that I never wore a full suit to a wedding, because I remember now that I once did. It was to an outdoor wedding in Dallas, during the summer of 2000, when they broke records for 100+ degree days. I was never more miserable in my life! And I had to be in a full suit because, though the wedding was outdoors, it was on the grounds of a super-ritzy hotel with a lavish reception afterward.
Then I went to another outdoor wedding at this place in Lafayette, CO that had chickens roaming the grounds. It was the wedding of my oldest friend and in addition to designing their invites, I was also the videographer. To that wedding, I wore only slacks and a button-up shirt.
It also depends on the people who are getting married! I probably could have worn a t-shirt to my friend's wedding and he wouldn't have cared, because he's like that. His brother said that if my friend ever got married again, he would wear nothing but a full-body condom to the wedding, something my friend would have whole-heartedly approved of.

Sadly, his brother died of an enlarged heart five years ago at the age of 25, and we held his wake at the... um... adult store next door to the funeral home.
So it's not an all-or-none deal, figuring out what to wear to an outdoor wedding.
