Posse Dresses: 10 Styles From Mini to Maxi and How They Fit

Posse dresses are made by Posse, the Australian womenswear label founded in 2016 by Danielle Mulham, and they cover every length from short cotton shifts to silk maxi slips. Most are cut from natural fabrics such as cotton, linen, silk and Tencel, many belong to a matching set of tops, skirts and shorts in the same fabric, and the brand says most styles fit true to size in letter sizes XXS to XXL.

This is the Posse dress edit from the newest drop on Coveti: ten dresses across mini, midi, maxi, slip and kaftan shapes, with how each one fits, what to wear with it and which set it belongs to. The drop mixes pieces from three Posse collections: Spring Summer 2026, Pre-Fall 2026 and Resort 2027.

Who makes Posse clothing?

Posse is an Australian womenswear brand founded in 2016 by Danielle Mulham. It is a family run, privately owned business, and it opened its first flagship store in New York City in 2026. The label sells through more than 80 stockists worldwide, including Net-a-Porter, Moda Operandi, MyTheresa, Le Bon Marche, Lane Crawford, Selfridges and Nordstrom.

Posse describes its approach as a devotion to quality, material and make. It says it chooses fabrics for how they feel, wear and last, and draws inspiration from people and places, old books and films, forgotten objects and antiques. That nostalgia shows in the dresses: lace trims, crochet edges, gingham, polka dots and vintage inspired embroidery. For the longer story, read who is Posse.

The Posse dress edit at a glance

Posse mini dresses

A mini dress is any dress that finishes above the knee. Posse’s minis lean toward shifts and A line shapes that sit away from the body, so they feel easy and work with flat shoes.

Tommy Dress in Ivory Black Polka Dot

The Tommy Dress in Ivory Black Polka Dot is a mini shift with a square neckline, bust darts and an off body fit, in cotton with a little elastane. The Tommy family also comes in a purple and ivory dot, and includes a top, a tee, a skirt and shorts. Wear it with black ballet flats and a small black bag so the dots stay the focus. Our guide on how to wear polka dots covers dot size and mixing prints.

Micah Dress in Red Gingham

The Micah Dress in Red Gingham is a mini with a boat neckline, an A line fit, a centre back zip and scalloped edges, in a mid weight structured knit that holds its shape. Its set partner is the Micah Cardigan in Red Gingham, slightly cropped, in the same knit with the same scalloped edges, so the two read as a twinset when worn together. The family also includes a halter top, a skirt, shorts and trousers.

Lila Mini Dress in Blue Gingham

The Lila Mini Dress in Blue Gingham is a scoop neck mini in loomed cotton gingham, A line and off the body, unlined for a light feel. It is the most relaxed dress in the edit: wear it with flat sandals for the weekend, and pull the oversized Lila Blouse over it on cooler evenings.

Darya Kaftan in Cream

The Darya Kaftan in Cream is a mini length kaftan in cotton and silk, with a deep V neckline, three quarter length wide sleeves, bust darts, a centre back zip, vintage inspired embroidery and a lining. Wear it alone as a dress, over swimwear at the beach, and over the matching Darya Skirt as a long tunic. Our guide on how to wear a kaftan dress goes through shoes and belts.

Posse slip dresses

A slip dress is a dress cut like a lingerie slip: fine straps, a fluid fabric and a body that skims instead of fitting. Posse makes two very different versions in this drop.

• The Tabitha Slip Mini Dress in Buttermilk is bias cut Tencel with a V neckline trimmed in sheer lace, soft gathers under the bust, a self fabric waist tie and a cotton voile lining. The bias cut follows the body, and the waist tie lets you adjust the shape.
• The Esme Slip Dress in Dusk is a midi length slip in pleated satin, with a lettuce edge hem, a separate scarf and a detachable waist tie. Wear the scarf at the neck for evening, and tie it at the waist for a different line.

Slip dresses look best with one structured piece on top: a cropped cardigan, a tailored blazer, a leather jacket. For more ideas, read how to style a satin slip dress.

Posse midi dresses

A midi dress falls between the knee and the ankle, usually around mid calf. It is the most useful length for work, weddings and lunches, because it looks dressed with both flats and heels.

Veda Sundress in Vintage White

The Veda Sundress in Vintage White is a cotton midi with short puff sleeves, a square neckline, a shirred elasticated waist and underbust, crochet lace at the neckline and hem, and a cotton voile lining. The Veda family is one of the largest in the drop, with a tunic, a top, shorts, a mini, a V neck maxi and an azure version of most pieces. See how to style a white sundress for shoes, underwear and the wedding rule.

Cynthia Dress in Chocolate

The Cynthia Dress in Chocolate is a sleeveless midi with a high neckline, a cinched waist with a snap button closure and flower detail, and an asymmetric hemline, in a double layered nylon and elastane fabric. Chocolate brown is a softer alternative to black for evening. Wear it with gold jewellery and a heeled sandal in tan.

Dean Dress in Black

The Dean Dress in Black comes from Resort 2027. It is a cotton velvet midi with a high rounded neckline, a fitted body, an asymmetric gathered skirt and a low scoop back, fully lined, with an invisible zip and hook and eye at the back. Posse designs it for a close body fit. The Dean family includes a velvet strapless top, a mini dress and a velvet drawstring purse, which makes an easy matching bag for evening.

Posse maxi dresses

A maxi dress reaches the ankle. Posse’s maxis in this drop are fluid and close to the body, made for evening and warm weather events.

The Blake Dress in Cloud Pink is a silk maxi that slips on, with a deep V neckline edged in contrast lace, pintuck detail below the bust, self fabric ties at the side seams and a double rolled hem. It is unlined and cut for a close body fit, so wear seamless underwear in your skin tone. Its set partners in the Blake family include a silk midi skirt with a tulle and lace hem and a matching silk top. More on this collection in the Posse Resort 2027 edit.

Other long Posse dresses in the drop include the Tabitha Maxi Dress in Blossom, which the brand calls a maxi length kaftan, and the Esme Strapless Dress, a pleated satin maxi with its own scarf.

How do Posse dresses fit?

Posse sizes run in letters from XXS to XXL, and Coveti lists the same letters. The brand describes most styles as fitting true to size, so take your usual size. Three fit notes appear across the dresses in this edit:

• Off the body and A line: the Tommy, Lila and Micah minis sit away from the body. These leave the most room through the body.
• Waisted: the Veda Sundress, Cynthia Dress and Tabitha Slip Mini Dress shape at the waist through shirring, a cinched snap waist and a tie. Check your waist measurement against the size you choose.
• Close body fit: the Dean Dress and Blake Dress are designed to sit close to the body. Choose your usual size and check the bust and hip.

For scale, the Posse house model Ploy is 173cm and wears XS. Some pieces in the drop are shown on taller models in size S, and each product page on Coveti notes the model’s height and size.

What to wear with a Posse dress

Wearing a Posse dress with its set

Because Posse designs in sets, each dress shares its fabric with tops, skirts and shorts in the same family. That gives you two ways to use the set. First, layer within it: the Micah Cardigan over the Micah Dress, the Darya Kaftan over the Darya Skirt. Second, swap a piece in: the Veda Short and Veda Top make a two piece version of the Veda Sundress for the beach. For more combinations, see how to style a matching set.

Shop every style in mini dresses, midi dresses and maxi dresses, and the whole label on the Posse brand page.
