Del Mar Opening Day Hats: How to Stand Out (and Enter the Hats Contest)

Del Mar Opening Day hats guide: what to wear to Opening Day at Del Mar, tips for the Opening Day Hats Contest, and the best fascinators for summer racing in Southern California.

Opening Day at Del Mar

Del Mar's summer racing season opens each July in Del Mar, California — "where the turf meets the surf." Opening Day is one of the biggest hat days in American racing, thanks to the Opening Day Hats Contest, which has been running for more than thirty years.

What to Wear to Del Mar Opening Day

Opening Day is dressy and fun. Expect sundresses, bright colors, linen suits, and plenty of creativity. The unspoken rule: the hat is the outfit's centerpiece. Build your look around your headpiece, then choose a dress that lets it shine.

• Coastal colors — coral, aqua, turquoise, lemon, white, and hot pink all suit Del Mar's beach setting.
• Breathable fabrics — it's mid-summer in Southern California.
• Walkable shoes — wedges or block heels handle the grounds better than stilettos.

How to Stand Out in the Opening Day Hats Contest

Contest hats tend to be bold, creative, and well made. A few tips from a milliner:

• Pick a clear idea. A theme — racing, the ocean, a garden, a color story — makes a hat memorable.
• Go big, but wearable. A large saucer or statement hat on a secure base lets you add drama without worrying about it slipping.
• Coordinate your whole look. Judges notice when the outfit and hat work together.
• Start early. A custom design needs time. Book a Style Consultation at least six weeks before Opening Day.

Not Entering the Contest? A Fascinator Is Perfect

A sculpted teardrop or fascinator headband keeps you cool in the California sun while still looking dramatic. Shop our Del Mar Opening Day hats and fascinators.
