Great choice. Effie Kats is Effie Kats is the Melbourne evening-wear house with a tailor's hand. Designer Effie Kats grew up in her family's workroom in the city's north, launched Zachary the Label at 23, and started again under her own name in April 2018 with made-to-measure suits and gowns. The ready-to-wear that followed keeps that fitting-room logic: gowns, bodysuits, capes and skirts cut close to the body in a signature stretch crepe, with square necklines, cinched waists, open backs and very little decoration. Coveti carries the current collection, sized XS to XL, which reads as AU and UK 6 to 14, and ships it worldwide.

The editor's guide to buying Effie Kats
Start with the gowns, because that is where the house starts. The Marbella, the Verona, the Monroe and the Inaya are continuity styles, cut in stretch crepe and sold in as many as ten colourways each, so a shade that sells out comes back. The Marbella has a square-neck bustier bodice and a cinched waist. The Verona has a high straight neckline and a low open back. The Monroe is the strapless one, with a folded panel at the bodice. The Inaya sits slightly off the shoulder with a back split. If you own one black gown from this label, one of those four is the sensible choice.
The second pillar is separates. Effie Kats designs its bodysuits, skirts and capes to be worn together, and the product pages say which piece goes with which: the Tia bodysuit with the Kayson skirt, the Charleze bralet with the Charleze skirt, the Bowie blazer with the Mereen skirt. A bodysuit under a blazer by day and over a long skirt at night is the house's own styling, and it is the cheapest way into the label.
For a black-tie evening, look at the capes. The Olympia, the Ashtyn and the Liberty are cut to go over a gown for the arrival and come off at the table. The velvet gowns, the satin Ricardo and the sequin Thalia and Kezio are the top of the range and arrive in small numbers.
Colour runs in families. Black, ivory and cherry red anchor the range. The seasonal shades have their own names, so Coffee and Chocolate are dark browns, Wine and Rio are reds, Squid is a slate grey, Truffle is an aubergine, Aspen is a pale blue and Parfait is a pale pink. Coveti's colour filter maps each one to a standard family, and the product name keeps the brand's own shade.

The stretch crepe has enough give that most customers take their usual size. Where a bodice is a bustier, size up if you sit between two; where it is strapless, size down so it grips. The Size and Fit note on each Coveti product page says which.
