Seven Parties. Seven Ways to Arrive.
Party Dressing Guide
What to Wear to Every Kind of Party, Decoded
There is a small cruelty built into every party invitation. It tells you the date, the time, the place, and the one word that decides everything, party, and then it tells you nothing at all. Because a party is not a dress code. An all-white soiree and a garden luncheon and a birthday that belongs entirely to you are three different rooms, three different lights, three different women, and one word will not dress you for any of them.
So this is the decoding. Seven kinds of party, seven ways they actually ask you to arrive, and the dress that answers each one without a second thought. Some want you to disappear beautifully into a rule. Others want you to be the reason the room turns. Knowing which is which is the entire art of it, and it is the difference between an outfit that works and one that simply attends.
Consider this your RSVP, answered in advance.
The 2026 Edit
Party Outfits for Every Invitation
01
All-White Party
The Mirabelle in White
The hardest dress code in the room, because the color is already decided and everyone honored it. When the palette is a given, the dress has nowhere to hide. Silhouette does the work. Fabric does the work. The way the light moves across you as you cross a terrace does the work.
Which is the argument for the Mirabelle Satin Maxi Dress. Liquid satin in white, cut long and fluid, catching light where a flat cotton would fall silent. In a sea of white it reads as the most considered version of the rule, not louder than the room, just more fluent in its language. A maxi length keeps it elegant rather than expected, and satin gives you the one thing an all-white party rewards above everything else: movement that photographs.
Keep the styling quiet. Gold at the ear, a slim heel, hair off the neck. The dress is the statement; everything else is punctuation. Our pieces generally run small, so size up one.
02
Cocktail Party
The Violetta for Cocktail Hour
The classic, and the most misread. Cocktail does not mean formal and it does not mean casual. It means elevated, deliberate, the mood of a woman who knew exactly how much to do and stopped one step before too much. The mistake is always overshooting into gown territory or undershooting into a dress you already own. The answer sits precisely between them.
The Violetta One Shoulder Gradient Dress lives in that exact space. The one-shoulder line is the statement, asymmetry doing what a busy embellishment never could, and the gradient carries a color story down the body so nothing else has to. It is a dress that looks like effort and wears like ease, which is the whole definition of cocktail done correctly.
This is where a real heel and a single crystal drop earn their place. One shoulder bare means the neckline and collarbone are the event, so let them be. Size up one.
03
Garden Party
The Vivienne in Pink
Florals, pastels, and a setting that is already doing a great deal of visual work before you arrive. The garden party trap is well known: wear something plain and you vanish into the hedge, wear something loud and you fight the flowers. The dress has to belong to the setting without dissolving into it.
The Vivienne Dress (Pink) was drawn for exactly this afternoon. A large-scale watercolor floral, painted and exclusive to us, cut into a halter with a ruched bodice and an asymmetric hi-lo ruffle hem that moves with the breeze rather than against it. The print is the whole styling concept on its own, which is why a garden is where it makes the most sense: it echoes the roses without competing with them. The hi-lo hem has a practical secret too, it keeps the front clear of wet grass while the back still reads as a full skirt.
Heels sink in turf, so choose a block heel or a wedge. Let the print carry everything else. The Vivienne is forgiving through the ruched bodice and self-tie halter, though we still suggest sizing up one.
04
Birthday Party
The Lily in Pink
The one party on this list that is unapologetically about you. Every other invitation asks you to fit into someone else's evening. This one asks you to be the reason it exists. That is not a night for restraint. It is a night for the dress you would not wear anywhere you had to share the attention.
The Lily Halter Pink Dress is built for main-character dressing. A halter mini in pink, cut to be seen and lit to be photographed, the kind of dress that makes a room understand whose night it is the moment you walk in. Pink is the correct birthday color because it is celebratory without trying, warm in every photograph, and impossible to read as anything but joy.
This is the night for the heel you have been saving and the earring that catches light when you laugh. Hair up, so the halter gets its moment. Size up one, and if the birthday is yours, take the dress that is a little too much. That is the entire point of it.
05
Dinner Party
The Josephine in White
A different kind of party altogether. Dinner is seated, close, and conversational, an evening measured in hours at a table rather than moments across a room. The dress has to hold up to proximity. It will be seen from a foot away, in candlelight, for a long time. Sophistication beats spectacle here, every time.
The Josephine Square Neck White Midi Dress understands the assignment. The square neckline is quietly flattering and quietly current, the midi length is refined without being severe, and white at a dinner table reads as composed and considered rather than costume. It is the dress that looks effortless precisely because it is not trying to be the loudest thing in a small room. It photographs beautifully seated, which is where you will spend the night.
Style it with a sleek heel and one clean piece of gold, or lean into the sophisticated-set direction with a tailored coat over the shoulders as the evening cools. Josephine is one of the styles we have confirmed runs closer to true to size, so take your usual size and check the guide.
06
Pool Party
The Belladonna in Black
The pool party has evolved. The version worth dressing for in 2026 is not a swim, it is a party that happens to have water in it, a rooftop at golden hour, a poolside dinner that runs into the night, a soiree where nobody actually gets in. That party has a dress code, and it is more elevated than a cover-up.
The Belladonna One Shoulder Black Dress is the after-dark answer to it. A one-shoulder line in black, sculpted and deliberate, the dress for the poolside evening that turns into an actual evening. Black at a pool party is a decision, a deliberate turn away from the expected brights, and it lands as the most grown-up look at the party once the sun drops and the lights come on.
This is the pool party dressed for the after, not the swim. Style it with a metallic sandal and let the one-shoulder line stay clean. Size up one. (See Flag 2: if you want the breezy, daytime, cover-up version of this section instead, this dress is the wrong tool and I would swap it.)
07
Tea Party
The Karina in Floral
The most specific dress code on the list, and the most rewarding when you get it right. Tea is ladylike by definition, an afternoon language of pastels, florals, and a certain deliberate softness. It is daytime, it is delicate, and it asks for romance rather than statement.
The Karina Open Back Floral Dress speaks it fluently, with one modern turn. The floral and the soft silhouette are pure tea-party romance, ladylike from the front and entirely at home over porcelain and cut flowers. The open back is the contemporary note, the detail that keeps the look from tipping into costume and keeps it firmly in 2026. It is demure and quietly modern at once, which is a harder balance than it sounds.
Style it with a low heel, a delicate crystal drop, and hair loose and soft. This is not the party for a statement shoe. Let the florals lead. Size up one.

Frequently Asked Questions
What do you wear to an all-white party?
An all-white party rewards silhouette and fabric over everything else, because the color is already decided for you. A liquid satin maxi, a lace mini, or a fluid white midi will read as considered rather than plain, which is the whole challenge of dressing to a color everyone else is also wearing. Keep accessories minimal and let the cut and the movement of the fabric carry the look. Avoid anything with a competing print, and choose a fabric that catches light, since flat, matte white can fall silent in a room full of it.
What does cocktail attire mean for a party?
Cocktail sits between casual and formal: elevated and deliberate, but not a gown. Think a polished mini or a midi dress with one strong design detail, a statement heel, and a single piece of fine jewelry. The most common mistakes are overshooting into floor-length formality or undershooting into everyday wear. A one-shoulder dress or an elevated mini is the safest read of cocktail, dressed enough to honor the invitation without tipping into black-tie.
What should you wear to a garden party?
Florals, pastels, and romantic silhouettes that belong to the setting without competing with it. A watercolor floral or a soft pastel in a flowing fabric is ideal, and a hi-lo or midi hem keeps you clear of wet grass while still reading as dressed. Choose a block heel or a wedge rather than a stiletto, since heels sink into turf. The goal is to look like you belong in the garden, not like you are fighting the flowers for attention.
What do you wear to a pool party in 2026?
It depends entirely on the party. A daytime, in-the-water pool party calls for a breezy dress, a set, or a glamorous cover-up over swimwear. A poolside evening party, a rooftop at golden hour, or a soiree where nobody actually swims calls for something far more elevated, and this is where a sculpted one-shoulder dress, even in black, becomes the most grown-up look at the party. Read the invitation and the hour before you choose, since the two versions ask for completely different dresses.
