The Wedding Guest Dress Code Guide: From Cocktail to Black Tie
Receiving a wedding invitation is a joy. Deciphering the dress code that follows? That can feel rather less straightforward. Cocktail. Semi-formal. Black tie optional. Each carries its own expectations — and the stakes of getting it wrong feel higher than almost any other occasion.
Consider this your definitive reference. We have broken down the four most common wedding dress codes, added guidance on day-versus-evening dressing, offered silhouette notes for different event settings, flagged a few colour cautions worth knowing, and addressed the perennial sequin question — all without pretending there is only one correct interpretation. Fashion, after all, is not a courtroom.
Cocktail Attire
The short version: polished, not casual — but not stiff either.
Cocktail is the most common wedding dress code and arguably the most liberating. It signals that the couple want their guests to look put-together without insisting on floor-length formality. The sweet spot is a midi or knee-length dress in a fabric with some weight or sheen — think crepe, satin, or structured jersey — rather than a sundress or bodycon.
Silhouette: A fitted or gently flared midi is the most versatile choice. Wrap silhouettes work across body types and tend to photograph beautifully. Mini lengths read as cocktail only when styled conservatively — sharp tailoring, covered shoulders, or an evening heel pulls the look up.
Day versus evening: For an afternoon ceremony, opt for lighter fabrics, softer colours, and minimal embellishment. Evening cocktail receptions invite more drama — richer tones, texture, and a bolder accessory.
Colour: Almost anything works at cocktail — including ivory and champagne at most modern weddings — though if you are uncertain, a deep or jewel tone is always a safe and elegant choice. Check our Midi Dresses and Mini Dresses for the current edit.
Semi-Formal Attire
The short version: one step below formal — the art of refined ease.
Semi-formal sits in the space between cocktail and black tie. It is a dress code that rewards intention: guests are expected to look dressed, not just presentable. A midi or maxi dress in a refined fabric — silk, chiffon, lace, or structured satin — reads exactly right. So does a tailored two-piece set.
Silhouette: Fluid and elongating silhouettes work well here. An A-line midi, a column maxi, or a draped floor-length dress all land comfortably within semi-formal. Avoid overly casual cuts — wide-leg linen trousers or wrap dresses in jersey — unless elevated with strong styling.
Day versus evening: Daytime semi-formal calls for lighter hues and lighter fabrics: blush, dusty rose, sage, pearl. Evening semi-formal can move toward deeper palettes and slightly richer textures. The silhouette can stay the same — let the colour and fabric do the tonal work.
Colour: White and ivory are generally best avoided as a courtesy to the couple, but beyond that the palette is open. Navy, forest green, champagne, deep terracotta, and dusty mauve are all perennial favourites for good reason. Browse Dresses & Sets for the full range.
Formal Attire
The short version: floor-length is not mandatory, but the feeling should be.
Formal weddings signal a desire for grandeur — typically large venues, seated dinners, and guests who have dressed with care. A floor-length gown is the most obvious interpretation and rarely wrong, but a refined midi with structured tailoring also holds its own, particularly for daytime formal events.
Silhouette: Go long where possible. A sleek column, a bias-cut slip, or a structured A-line gown all serve formal settings well. Asymmetric hemlines, high slits, and sculptural necklines can add editorial interest without undercutting the formality of the look.
Day versus evening: A formal daytime wedding — often in a stately home, garden, or place of worship — may call for covered shoulders and softer, more muted tones. Formal evening is where you can lean fully into drama: deep jewel tones, rich metallics, and considered embellishment are all appropriate.
Colour: White and ivory remain the clearest colours to avoid. Beyond that, almost every shade and depth of colour is fair game at a formal wedding — the weight and quality of the fabric will communicate formality more reliably than the colour itself. See our Maxi Dresses and Party & Evening Dresses for formal-ready options.
Black Tie Attire
The short version: this is as formal as weddings get — and a genuine opportunity to dress with intention.
Black tie is the most explicit of all dress codes. It signals a desire for full evening formality, and guests are expected to reciprocate. A floor-length gown is the traditional — and most straightforward — interpretation. That said, a structured, heavily embellished midi in a luxurious fabric can also work in certain settings, particularly for younger, fashion-forward guests attending urban or venue-led receptions.
Silhouette: Long and considered. Strapless, one-shoulder, halter-neck, and draped column silhouettes are all fitting. The overall look should feel complete: every detail — shoes, jewellery, bag, and hair — should be chosen with the same level of intention as the dress itself.
Day versus evening: Black tie is almost always an evening occasion. If a rare daytime black-tie event appears on your calendar, lean toward paler, more refined tones rather than full evening metallics — the light will do the work that sequins do after dark.
Colour: Black, midnight navy, deep emerald, rich burgundy, and full metallic are all effortlessly appropriate. White and ivory are best reserved for the wedding party. Lighter pastels can work beautifully if the fabrication and silhouette are suitably formal — a pale blush silk column, for example, reads as elegant rather than casual.

On Sequins: A Note
Sequins divide rooms. Some guests feel they belong exclusively to the night; others wear them to Sunday brunch without a second thought. At weddings, the relevant question is not whether sequins are allowed — it is whether they suit the setting and time of day.
For cocktail and semi-formal evening receptions, a sequin midi or a partially embellished dress is entirely appropriate and often very welcome. For formal or black-tie evening events, full sequin gowns are a strong and legitimate choice. For daytime ceremonies, lean toward subtler shimmer — metallic threads woven into fabric, or tonal embellishment — rather than full-coverage sequins, which can read as overwrought in natural light.
The general principle: the later the celebration begins, the more confident you can be with embellishment.
A Few Colour Notes Worth Keeping
White and ivory are widely understood as colours to avoid at weddings out of deference to the couple — though modern couples vary in how strictly they hold this convention. If you are uncertain, a quick and gracious message to the couple or wedding party is always the most considerate approach.
Red is sometimes cited as too attention-drawing for a wedding guest. In practice, the shade and styling matter far more than the colour itself — a deep burgundy midi is a world away from a fire-engine red minidress. Use your judgement.
Blush and champagne can read as bridal in certain lights and at certain weddings. If the invitation suggests a traditional ceremony, it is worth considering an alternative. At a relaxed, modern celebration, these shades rarely raise an eyebrow.
