How to think about a funeral dress code
The most reliable guide is the family. Obituaries, invitations, and messages from organizers sometimes name a dress code, a favorite color, or a request for casual clothes. When they do, that request matters more than any general custom. House of worship and community expectations come next.
Without guidance, many people choose clean, modest clothing in dark or muted colors, one step more formal than everyday wear. Faith and cultural customs may differ from this, for example around white clothing, head coverings, or removing shoes, and practices vary between communities and families. When in doubt, ask someone close to the family. Then plan for the practical parts of the day: time outdoors at a burial, the weather, and shoes you can stand in comfortably.
