Acler for Black Tie: Gowns and Maxi Dresses for Formal Weddings

A black-tie invitation is the easiest dress code to read and the hardest to shop for: it asks for a floor-length dress, a fabric with some weight and nothing that looks like daywear. Acler, the Adelaide label known for hand-draped event dressing, is one of the more reliable answers. Its long dresses are structured through the bodice, lined, and built to hold their shape for a full evening. This guide covers the best Acler gowns and maxi dresses for a black-tie wedding, a formal gala and mother-of-the-bride dressing.

What black tie means for a dress

For women, black tie means a floor-length gown, and in most places a very formal cocktail dress will no longer pass. Rich colours and solid fabrics read as more formal than pale prints. Metallics and deep jewel tones work well at night, and sleeves and coverage are a choice, not a rule. The one thing to avoid at a wedding is white and ivory, which belong to the bride. Our black-tie dresses guide covers the code across every label.

Acler gowns

Acler labels its most formal pieces as gowns. The Adcote Gown in Dove is the one for a guest: a soft grey that photographs beautifully and stays clear of the bride’s colours. The ivory gowns, the Sageston, Kenley and Harty, are for brides and for galas where white is welcome; see our white Acler dresses guide for those.

Maxi dresses that work as black-tie gowns

Most of Acler’s maxi dresses are formal enough for black tie, especially in deep colours. These are the strongest by colour.

Jewel greens

The Hertfordshire Maxi Dress in Midnight Emerald and the Reeve Maxi Dress in Deep Emerald are two of the most formal greens Acler makes. The Gilwell Maxi Dress in Deep Emerald is softer.

Blues

Blue is Acler’s strongest colour this season. The Hertfordshire in Deep Sapphire, the Mannetto in Sapphire and the Piddington in Night Sky are all deep enough for an evening wedding.

Metallics

For a gala more than a wedding, the Anslow Maxi Dress in Gold, the Mapstone Maxi Dress in Golden and the Kelsale Maxi Dress in Silver Metallic catch the light without needing jewellery.

Reds and berries

The Hertfordshire in Cherry, the Humfield in Garnet and the Realbart in Deep Mulberry are the confident choices for a winter wedding.

Black

The Hertfordshire Maxi Dress in Black and the Broadhay Maxi Dress in Black are the safest answers to black tie, and the easiest to wear again.

The new one: the Primula Maxi Dress

The Primula Maxi Dress in Bordeaux Haze is the newest Acler long dress on Coveti, from the third Fall 2026 drop. It is a floor-length gown in lightweight woven polyester under a sheer overlay, with a fitted bodice, adjustable cami straps and a sunray-pleated skirt carrying a placement print that shades from pale pink to deep wine. Acler itself tags it for black tie, wedding guest and mother-of-the-bride dressing. Match it to the Drip Birch Bag in Bordeaux Haze, which uses the same colour.

Acler for the mother of the bride

Mother-of-the-bride dressing needs coverage, comfort for a long day and a colour that sits well with the wedding palette. Acler is good at this because its shapes are structured without being stiff. Look for a long dress in a soft colour, ideally with a sleeve and a higher neckline: the Adcote Gown in Dove, the Glatton Maxi Dress in Misty Blue and the Harden Maxi Dress in Powder Blue all suit a daytime ceremony. For an evening wedding, the deeper blues and the Primula are the better fit.

Shoes and bags for black tie

Under a floor-length gown, the shoe barely shows, so comfort wins. A strappy sandal on a moderate heel, like the Acler Brinlee Heel in Sepia at 7 cm, will last the night. The bag is where a black-tie look can take a risk: a hand-beaded evening bag like the Birch Bag in Spicy Red gives a black dress a point of colour. Our guide to Acler shoes and bags covers the full range, our beaded evening bags guide compares the bags with other labels, and ivory bridal heels covers the shoes for the bride.

Sizing a long Acler dress

Acler cuts AU 6 to AU 16, which match UK sizes number for number; a US size is four lower. Long dresses are made for a model around 175 cm, so if you are petite, expect to hem a floor-length style, and if you are tall, check that the dress is listed as a maxi rather than a midi. Our Acler mini, midi and maxi guide explains the lengths.

Black tie and mother of the bride in the UK, Canada and the UAE

United Kingdom

Black tie dresses are one of the biggest formalwear searches in Britain, and mother of the bride outfits nearly as big. For a British black-tie wedding, a long sleeve maxi dress is the most searched shape, and it is the safest answer for a church ceremony and a cold evening alike. The Hertfordshire Maxi Dress has long sleeves and comes in Midnight Emerald, Deep Sapphire, Cherry, Dove and Black, so one style covers most invitations. For the mother of the bride, the Hertfordshire in Dove is soft enough for daylight photographs. Acler sizes match UK sizes exactly.

Canada

Canadian searches for fall and winter wedding guest dresses rise from August and peak through the autumn. A long sleeve gown in a deep colour is the answer to both: the Stamford Maxi Dress in Shadow Green and the Robakker Maxi Dress in Iris Blue both have long sleeves. Canadian sizing follows US sizing, so a US 8 is an Acler AU 12.

United Arab Emirates

In the UAE, evening gowns and Eid dresses are searched more often than black tie itself, and many occasions call for coverage. Acler’s long-sleeved and high-neck maxi dresses suit both: the Hertfordshire, the Hanwell Maxi Dress in Metallic Sepia for an evening with some shine, and the Lansvale Maxi Dress in Night Sky with its high neckline. A hand-beaded Drip Birch Bag finishes a plain gown.

Coveti ships Acler to all three countries by DHL Express and FedEx International Priority. Local duties and taxes may be payable on import. Browse every style in evening gowns and maxi dresses.
