The classic mother of the bride coat dress is a favourite among the likes of Princess Kate, Zara Tindall, and Princess Beatrice, loved for being a timeless cover-up that's smart, yet feminine. There's barely a royal engagement go by where you don't spot a royal wearing one.

A coat dress ticks all the boxes for many an occasion, from weddings to christenings to the races, and can be as modest (think long sleeves and midi length) or as sexy (a mini blazer or tuxedo dress is uber chic) as you need, or want, it to be.

What is a coat dress?

A coat dress is a dress that has coat elements. Usually with a collar or lapel, they can be opened by a front enclosure, typically buttons. A coat dress is often made from slightly thicker material than cotton, and most commonly has long or three-quarter sleeves, although there are sleeveless options.

The most popular type of coat dress is the style Princess Kate wears, with a fit-and-flare silhouette that nips in at the waist with long or half-sleeves, and has either has a collar or wider neckline with lapel.

If Kate’s style is a little too classic for you, look to Meghan Markle for your more modern coat dress inspiration. The mum of two favours the tuxedo dress, a cooler version of the classic coat dress that is essentially an elongated version of a blazer or tuxedo suit jacket.

When to wear a coat dress

Occasion wear and coat dresses go hand in hand – you can wear one to Ascot, a christening or a wedding. You'll find coat dresses for weddings a popular choice as a mother of the bride outfit, or mother of the groom of course.

How to wear a coat dress

Wearing a coat dress is easy, as it’s a one and done type of outfit. They work best with a closed-toe heeled shoe, such as a court shoe, or a heeled espadrille - Princess Kate and her Catherine Walker coat dresses really are your best reference. Due to their tailored nature, a structured bag or clutch is your ideal accessory.

How I chose the best coat dresses for women

  • Royal inspiration: Having written about royal style for the past six years at Best Quality Designer Handbag , I'm au fait with the types of dresses our favourite royals wear and I've found as many high street versions that have all the markings of a royal worthy coat dress.
  • Price: The very nature of a coat dress means that, a lot of the time, it comes with a high price tag but I've done some digging to find a few that are on the more affordable side.
  • Availability: All of the pieces were available in a variety of sizes at time of publication.
