What color is the groom's mum supposed to wear?

The groom's mother is free to wear almost any colour, as long as it suits the occasion and the couple's wishes. The key rule is to avoid white, ivory or anything that could look like a bridal outfit. She should also steer clear of black at a daytime wedding, unless the couple has asked for formal evening wear.

It helps to ask the bride or the mother of the bride what the bridesmaids are wearing. This keeps the family photos balanced and avoids two people looking identical. A mid-length or full-length dress in a soft jewel tone, floral print or muted pastel works well for most ceremonies.

• Ask the couple if there is a colour palette or theme.
• Check the venue and time of day before choosing fabric and length.
• Avoid anything too revealing or too flashy for a place of worship.

If the wedding is religious, some places of worship ask guests to cover their shoulders. The rules can vary, so check with the register office or the place of worship if you are unsure.
