In bars or club gigs I dress very unformally (I used to dress quite formally everywhere, but gave up in these kind of gigs). In private parties or wedding parties I do dress formally, with black pants and black shirt. Very often, also with a white dinner-jacket (in the summer: linen). And because a "picture is worth a thousand words" take a look here (I already took off the jacket): http://vega.estig.ipb.pt/Photo/Photos1/picture-001.html http://vega.estig.ipb.pt/Photo/
