Our guild is "anything goes". I have never given it any thought before this post on appropriate dress for guild meetings. Comfort is the important thing for us. Any where from dress clothes to sweats. I coach basketball, so I have come from practice in sweats to meetings, and no one has said anything about it. I usually come from work, unless it is summer, and never feel over dressed. We are just glad people are there and want them to feel comfortable no matter what they wear.
