What to wear to a wedding: dress codes, decoded

6 min read

Wedding guests drawn in what each dress code asks for: evening gowns and dinner suits, cocktail dresses, garden florals and light linen

A dress code on an invitation is a kindness: it tells guests how dressed up the day will be, so nobody arrives in linen to a ballroom. The trouble is the words, which mean more to some guests than others. Here is what each one asks for, from black tie down to smart casual.

Black tie

The most formal code most weddings use. Floor-length gowns, or an elegant cocktail dress in a rich fabric; a dinner suit with a bow tie for the men. Black tie belongs to evening weddings, usually indoors, often with a seated dinner.

Wedding guests in black tie: long gowns in navy, burgundy and emerald, and a black dinner suit

Formal, or black tie optional

One step down. Long dresses or dressy cocktail dresses, and dark suits with ties; a dinner suit is welcome but not expected. When an invitation says black tie optional, the couple will be in black tie and would like the room to be close to it.

Wedding guests dressed formally: long grey and blush gowns and a dark suit

Cocktail

The most common code, and the easiest. Knee or midi length dresses, a smart jumpsuit, dressy separates; suits, with or without a tie. Colour and pattern are welcome; the effect should be polished rather than grand.

Wedding guests in cocktail dress: short black, beige and green dresses and grey and navy suits

Semi formal

Between cocktail and smart casual, and it moves with the hour. In the day, lighter suits and summer dresses; in the evening, darker colours and a little more polish.

Wedding guests in semi formal dress: floral and blue dresses, a camel jacket and a grey suit

Garden party

Florals, midi dresses, soft colours, a hat if you like one; linen or light suits, a tie optional. Choose block heels or flats over stilettos, which sink into the lawn, and bring a layer for the evening.

Beach formal

Formal in spirit, light in fabric. Flowing maxi dresses and breathable fabrics; linen suits, no tie, shirts open at the collar. Flat sandals rather than heels, and nothing that minds a little sand or salt.

Wedding guests in beach formal dress: flowing white, blue and coral dresses and linen shirts and trousers

Smart casual

Relaxed, not careless. Summer dresses, smart trousers, a blazer over a shirt without a tie. Jeans only if the couple say so, and trainers only if they are very clean and the invitation is very relaxed.

When the code is a colour

More couples now give a palette rather than, or as well as, a dress code: pastels, jewel tones, earth tones, all white. It is an invitation to dress in those colours so the photographs come out as one picture. Choose something in the palette, and if the palette is all white, that is the one time white is right.

On a MyEventOS invitation, the dress code page shows the code with a drawing like these and the colours the couple would like to see, so guests can picture it before they shop.

Whatever the code

  • Do not wear white or ivory unless the couple ask for it.
  • Dress for the place: covered shoulders for some religious ceremonies, flat shoes for grass and sand.
  • Bring a layer for the evening, when an outdoor wedding cools down.
  • When in doubt, dress one step up. Nobody minds an overdressed guest.

Questions people ask

Can I wear black to a wedding?

Usually, yes. Black is at home at an evening or a formal wedding. For a daytime or summer wedding, a colour reads more celebratory, and some families still prefer guests not to wear black, so check if you are unsure.

What does black tie optional mean?

That the couple will be in black tie and would welcome guests in it, but a dark suit and tie, or a long or dressy cocktail dress, is perfectly correct.

What if the invitation has no dress code?

Read the rest of it: the time, the place and the tone of the words. An evening at a hotel suggests cocktail or formal; an afternoon in a garden suggests garden party. If still unsure, ask the couple.
