Design-led looks that photograph beautifully

Each piece in this edit has been selected from Australian designers known for quality and occasion dressing. These are boutique race day dresses designed to make an entrance and stand out in every photograph.

Our range includes both minimalist and maximalist options to suit different events and personal preferences. You can go bold with sculptural volume or keep it classic with clean tailoring and a flattering neckline.

These pieces are built for comfort over long days in the sun, while maintaining shape and elegance throughout the event.

If you're planning for the full look, many of our dresses pair beautifully with hats, headbands and fascinators — just keep accessories polished and in line with the dress code of the day.

FAQs

Many of our race day dresses are well-suited to formal and semi-formal racing events such as the Melbourne Cup, Derby Day and Oaks Day. However, we recommend reviewing the dress code for your specific event to ensure your outfit meets all requirements.

Most styles are crafted from breathable materials suited to spring and summer wear. Look for pieces with lightweight fabrics, open necklines and sleeveless options (if the dress code permits) for all-day comfort.

Absolutely. Many of our dresses for races pair beautifully with headwear. Choose headpieces that complement the colour and silhouette of your dress while keeping balance in your overall look.

Most styles in this collection are designed with traditional race day guidelines in mind, including modest necklines, appropriate lengths and refined finishes. However, we always recommend checking the specific dress code for the event or enclosure you're attending, as requirements can vary between venues and days.
