St. Agni Dresses: Halter, Slip, Balloon and Column Shapes

St. Agni dresses come in four main shapes: the halter, the slip, the balloon and the column, almost all cut long, in silk, silk-linen, cotton blends and TENCEL jersey. The St. Agni edit in Coveti’s designer dresses runs to 41 dresses across 27 styles, and the clearest place to start is the Silk Handkerchief Halter Dress in Stone, a 7/8-length silk halter cut slim through the body.

Key Facts

  • St. Agni is an independent design studio founded in Byron Bay in 2014 by Lara and Matt Fells.

  • Fabrics include 100% silk, 100% Tussah silk, a 65% silk and 35% linen blend, and TENCEL Lyocell jersey.
  • Dresses are sized XXS to XL, and St. Agni sizing is Australian, which matches UK sizing.

How St. Agni Approaches a Dress

The label began with footwear, moved into accessories and only then into clothing, so the dresses arrived with a shoemaker’s habit of stripping things back. Most are solid colours, and most are sleeveless. The interest sits in the neckline, the back and the length, which is usually 7/8 (falling around the lower calf) and occasionally a full maxi.

The colours follow the same discipline. Stone, Bark, Porcelain, Wood, Soft Ash, Iron Glaze, Washed Black: the names change from season to season but the palette stays close to sand, clay and charcoal. It is a wardrobe built to be repeated, which is why the brand turns up again and again in conversations about quiet luxury.

Halter Dresses

Halters are the backbone of the summer offer, and the four styles are more different than their names suggest.

Silk Handkerchief Halter Dress

The purest of the four. One fabric, 100% silk, a halter neckline and a 7/8 hem, cut slim. It comes in Stone and in Bark, both warm neutrals that sit well against a tan and work with gold jewellery. This is the dress to buy if you want one St. Agni piece for a wedding season and a holiday.

Halter Wrap Backless Dress

The Halter Wrap Backless Dress in Porcelain uses a cotton blend with linen and a little spandex, which gives it more body than silk and makes it easier to wear on a long day. The halter wraps at the neck and the back is open. It also comes in Wood, a muted green.

Halter Circle Hem and Woven Check Halter

The Halter Circle Hem Dress in Off White is the only full maxi of the four and has a halter-wrap neckline over a slim body. The Woven Check Halter Dress in Soft Ash is cut in a silk-linen blend with a fluid drape and an adjustable buttoned neck, so you can set the halter higher and lower. For a longer read on wearing all of these, see our guide to halter maxi dresses.

Slip and Cami Dresses

The Silk Twill Relaxed Slip Dress in Milk is the one relaxed silhouette in this group: a v-neckline, a 7/8 length and room through the body. The Cami Dress in Wood goes the other way, with a sweetheart neckline and a fitted cut to maxi length in a cotton, nylon and linen blend.

The slip is also part of the brand’s celebrity record. Grazia reported that Kendall Jenner wore a high-neck slip dress from St. Agni’s WOMAN collection, along with a white cami from Resort 2022. These are past-season pieces, not the styles above, but they show how long the slip has been central to the label.

Balloon Dresses

Volume is the newer story at St. Agni, and it runs from balloon pants through skirts, tops and dresses. The Strapless Balloon Hem Dress in Cedar pairs a strapless knit bodice with a skirt that gathers in at a 7/8 hem; the brand describes it as a fitted bodice with a relaxed skirt. The Raw Silk Asymm Balloon Dress in Cloud Cream, from Resort 2027, has a strapless knitted bodice and a draped, pleated skirt in a Tussah silk blend.

Both are strapless, so the fit at the bust matters more than usual. Size to your bust measurement, not your hips, since the skirt has the room.

Column and Wrap Dresses

The Silk Wrap Dress in Washed Black has a cowl neckline at the front and a wrap back fastened by a rouleau tie, in 100% Tussah silk. It is the most evening-appropriate dress in the range and also the easiest to dress down with a flat thong sandal. The Fine Jersey Circle Hem Dress in Charcoal sets a knitted bodice with an asymmetric neckline and sleeve over a full circle skirt in TENCEL jersey. It is the one to choose if you prefer a sleeve and a softer fabric.

In April 2026, Meghan, Duchess of Sussex, was photographed wearing a black backless halterneck St. Agni dress at a Sentebale dinner in Florida, according to Grazia and Marie Claire. The exact style was not confirmed by either report.

Fit and Sizing

Nearly every dress here is sized XXS to XL, and the brand notes that its Australian sizing matches UK sizing. Most product pages list the model’s height and size: the halter and wrap styles are shown on a 178cm model wearing an XS, and the Woven Check Halter on a 178cm model wearing an S. Because the 7/8 length is designed to end on the lower calf, shorter wearers will find it lands closer to the ankle. Our St. Agni size guide covers the conversions in full.

How to Wear Them This Summer

With the Southern-hemisphere summer starting, the halters and the cotton-blend styles do the most work. Keep shoes flat and simple: a leather thong sandal, a ballet flat, a slide. Add one structured bag. Skip the statement necklace, since the necklines are the detail. For travel, roll the silk styles in tissue and hang them on arrival; the cotton blends are more forgiving in a suitcase. Our edit of vacation dresses has more holiday pairings, and the summer capsule wardrobe shows how one St. Agni dress fits into fifteen pieces.
