[header] How to act at a funeral [title] Dress conservatively. [step] When attending a funeral, always dress conservatively. Do not wear flashy outfits, bright colors, baggy clothing, or low-cutting blouses or dresses. 
You do not have to wear all black, but at least dress in darker colors, like dark blues, greens, and grays. As a general rule of thumb, dress business casual when attending funerals.
