What are the top 6 things I should never wear as a wedding guest?

The main rule is simple: your outfit should not upstage the couple. The most important thing is to avoid white or anything that could be mistaken for a wedding dress, including ivory, cream and very pale pastels. If in doubt, choose a different colour.

Next, think about modesty and comfort. Extremely short hemlines, low necklines or see-through fabrics can look out of place in many settings, especially in a place of worship. Dress respectfully and choose something you can sit, dance and eat in comfortably.

Avoid anything too casual like trainers, jeans, shorts or sportswear unless the couple has specifically asked for it. Loud accessories such as big hats that block views, jangling jewellery or flashing lights are also best left at home.

Finally, full black from head to toe can look funereal in some settings, so soften it with a colourful top or accessory. If the invitation suggests a theme or dress code, follow it, but when in doubt, ask the couple or a member of the bridal party.
