It sounds so straightforward, but given the vague nature of 'formal attire' and its close affiliation with terms like ‘lounge suit’, ‘suit and tie’ and ‘black-tie optional’, it’s little wonder a formal wedding dress code can leave guests second-guessing their wardrobe choices. To help, ABIA take a closer look at what a formal dress code means, break down what’s expected and offer suggestions for men’s and women’s formal dressing.

Defining a formal wedding guest dress code

On a scale of wedding dress codes, formal falls toward the more polished end of the spectrum. It’s a step above cocktail attire and below black-tie dressing though, in truth, there’s often a little overlap. Essentially it calls for a refined and classic look, while still allowing for a touch of personal flair.

Often used interchangeably with other dress code labels, like ‘lounge suit’ and ‘black-tie optional’, a formal look typically asks for men to wear a full suit and tie, while women are expected to wear elegant dresses or polished separates in dressy fabrics. Think timeless silhouettes, sophisticated accessories and a generally elevated vibe.

Dresses

Floor-length maxi or midi dresses are ideal, though structured knee-length options may work depending on the venue and time of day
Think refined silhouettes in luxurious fabrics like satin, crepe, chiffon, silk or velvet
A well-tailored jumpsuit in a formal fabric may offer a stylish alternative, as may a dressy blouse paired with a midi or maxi skirt or high-waisted tailored trousers

Shoes

Closed-toe heels, sleek pumps or formal dress sandals

Accessories

Clutches or elegant handbags and equally elegant jewellery
