Garden Party Dresses: What the Dress Code Means and What to Wear

A garden party dress is a smart daytime dress, usually a midi in cotton and silk, in colour and print, cut to stay cool in the sun and worn with shoes that will not sink into the lawn. Our midi dresses edit is the obvious place to look, and the Ulla Johnson Pre-Spring 2027 collection is full of striped poplin, floral silk and fringed knits that suit a lawn. For a looser shape, see our tiered maxi dresses guide.

Key facts

• A garden party dress code usually sits between smart casual and cocktail, and calls for a smart daytime dress.
• A midi is the safest garden party length because it clears a damp lawn and handles a breeze.
• Block heels, wedges, espadrilles and smart flats suit grass, while stilettos sink into the lawn.
• Ulla Johnson Pre-Spring 2027 includes striped cotton poplin dresses and silk crepe de chine floral midis suited to garden parties.

What does a garden party dress code mean?

A garden party is a daytime event outdoors, and the dress code usually sits between smart casual and cocktail. Think of it as the dress you would wear to a summer christening and a long lunch: polished, pretty and comfortable for standing on grass for three hours. Formal garden parties in Britain often expect a hat and a fascinator, and a dress to the knee and below. A private party in a friend’s garden is looser, and a printed sundress and a smart skirt and blouse both work.

Fabrics that survive heat and lawns

You will be in the sun, so breathable natural fibres are the first rule.

• Cotton poplin is crisp, cool and holds a stripe sharply. It creases, but in a relaxed way.
• Silk crepe de chine is light, drapes well and carries a print beautifully.
• Silk chiffon floats in a breeze and looks lovely in photographs, though it needs a lining.
• Cotton jacquard knits have more structure and suit a cooler day.

Avoid heavy satin in full sun, since it shows every mark, and pale silk that will reveal damp patches.

Hemlines and shoes for grass

A midi is the safest length. It looks smart, it handles a breeze and it stays clear of a damp lawn. Floor-length dresses drag on grass and pick up stains, so if you love a maxi, choose one that clears the ankle. For shoes, stilettos sink straight into the lawn. Block heels, wedges, espadrilles and smart flats all work. Heel protectors that clip over a stiletto are an option if you must.

How to wear a garden party look

• Choose one statement piece, a bold print perhaps, and keep the rest quiet.
• Bring a layer. A cardigan and a light jacket see you through a cool afternoon in early summer.
• Pick a hat with a brim for full sun, a smaller headpiece for a formal event.
• Carry a structured bag you can hold with a glass in the other hand.
• Wear sunscreen on the shoulders if your dress is sleeveless.
