Now that you know what the expected level of dress is, it’s time to address the Do’s and Don’t's of wedding guest apparel.

For her:

• Don’t try to upstage the bride- all attention should be on the bride’s dress, not yours. This means no tiaras or outlandish dresses.

• DO NOT wear all white because it competes with the bride. White or cream is only appropriate when worn in a floral print or if it isn’t the dominant colour in an outfit.

• Nowadays black is acceptable to wear to a wedding, though if you’re unsure if the happy couple will take offense, either ask first or opt for another dark colour instead. However, this colour is usually reserved for evening events only. A statement piece of jewellery or another colour can break up the dominance of black.

• For religious weddings you will need to dress accordingly- this usually means avoiding strapless or sleeveless outfits, and take a wrap to cover your shoulders.

• Gloves should be taken off to eat or drink.

• Sequins should be reserved only for night-time.  

• Avoid high heeled shoes that will sink into the grass if it’s an outdoors wedding.

• You’re going to a wedding, not a nightclub. This means the overtly sexy clothes stay at home in the wardrobe- that’s anything see-through, too revealing or too short.

• For hot climates steer clear of the suit and go for a dress in light fabrics to keep you cool.

For him:

• Regardless of the formality, tuxedos are not daytime wear.

• Do not wear jeans at all.

• If in doubt, opt for a dark suit and tie.

• When wearing a suit, try not to look like you’re going to the office.

• Don’t mix too many patterns or textures- a pinstripe suit, striped shirt and striped tie can result in an unfortunate clash.

• When choosing a tie, make sure that it’s appropriate- save your Simpsons tie for another time. If you’re unsure about patterns, ask for a store assistant’s help (after all, that’s their job and they usually have a good idea of what works) or stick to a plain colour.

• When it comes to beach weddings or those in hot climates, the rules are a little different- choose light fabrics that will keep you cool and it is usually acceptable to ditch the jacket. If you’re unsure, just ask the couple.

When looking for an outfit, it isn’t practical to spend a lot of money on something that’s never going to be worn again. A convertible dress can be worn in many ways and will always look different so it doesn’t appear that you’re wearing the same outfit twice. Hiring or renting formal clothes is an inexpensive alternative to buying a designer brand.
