Purple Evening Gowns: Amethyst, Plum and Lilac Gowns for Formal Nights

Purple is the colour for women who want to stand out at a formal event without wearing red. It has a long association with royalty, it flatters most skin tones, and almost no bride wears it, which makes it a safe colour for a wedding guest. Here are the purple evening gowns we would choose at Coveti, from deep amethyst to pale lilac.

The statement: Avaro Figlio Amethyst Royal Purple Crystal Gown

The Amethyst Gown is the strongest purple gown of the Fall Winter 2026 season. It is covered in royal purple crystal embellishment over a fitted, ruched body, with a deep V-neckline and long sleeves. Made to order in Milan by the couture house Avaro Figlio, it is $2,570 at Coveti and works for a black tie wedding, a gala and a winter ball.

The quieter purple: Avaro Figlio Midnight Edge Off-Shoulder Cady Dress

If crystal from neck to hem is too much, the Midnight Edge Dress is cut in rich purple cady with floral embroidery. Long kimono sleeves and a draped front give it movement without embellishment. $2,490.

Deep plum and aubergine

Plum is purple with red in it, warmer and softer under candlelight. Carolina Herrera cuts the Sofia Gown in Plum, and Alex Perry has two satin crepe gowns in the shade: the Long Sleeve Knot Gown and the Off Shoulder Panelled Gown. Simkhai calls its version Fig; see the Ora Satin Gown.

Royal purple and violet

For a true violet, Viktor and Rolf makes the Bow Volant Corset Gown in Purple, a corseted gown with the house’s signature bow. Saiid Kobeisy works in a shade it calls Italian Plum, including the Sequin Embroidered Long Dress.

Lilac and lavender

Lilac is the spring and summer purple, and it suits a daytime wedding better than an evening gala. Safiyaa makes the Joulia Lilac Snow Gown, Alexander McQueen has the Bustier Evening Dress in Lilac, and Maria Lucia Hohan makes the Despina Gown in Lilac.

How to wear a purple gown

Jewellery: silver and diamonds with cool purples, gold with plum. Shoes: silver sandals for crystal gowns, a black satin heel for cady. Bag: a small metallic clutch. Make-up: keep the lip neutral and let the colour of the gown lead. On a crystal-covered gown such as the Amethyst, wear nothing at the neck.

Which purple for which event

For a black tie wedding and a gala, choose amethyst, violet and plum in a heavy fabric. For a summer evening wedding, choose lilac chiffon. For a winter wedding, see our guide to winter wedding guest dresses.

Frequently asked questions

Is purple a good colour for an evening gown?

Yes. Purple is regal, flattering on most skin tones, and rarely worn by brides, which makes it one of the safest bright colours for a wedding guest and a strong choice for a gala.

What shade of purple suits a winter event?

Deeper shades: amethyst, royal purple, plum and aubergine. Lilac and lavender read as spring and summer colours.

What jewellery goes with a purple gown?

Silver and white gold suit cool purples such as amethyst and lilac. Gold suits warmer plum. Keep jewellery minimal on a crystal-embellished gown.

What shoes go with a purple evening gown?

Metallic silver, nude and black all work. A satin heel in the same purple is a strong evening look.
