It's a classic etiquette rule that spans multiple cultures. You don't want to wear white to upstage the bride, and you don't want to wear black to mourn such a happy occasion. Lady Sarah Chatto didn't get the memo at Zara Phillips' wedding.
Want to be a rule-breaker? Wear an off-white color. Mix in colorful or even black accessories and you're neither stealing the show nor mourning a loss.
If you're at a fancy, British wedding, you're almost always expected to wear a fashionable, sometimes over-the-top hat. Don't let the hat overcome your look though. Katherine Kelly looks perfectly put together at Zara Phillips and Mike Tindall's wedding, but the hat is a little extra.
When in doubt, a manageable fascinator is all you need—and you'll actually be able to see what's going on.
While her colorful frock was no doubt lovely, Cressida Bonas was a bit distracting and seemed more suitable for a less formal event than her ex-boyfriend Prince Harry's wedding.
While she kept the silhouette on-trend for English nuptials, Pippa gave us a delicate but unexpected print that paired perfectly with the blush pleats.
It's a very common trend among high society to wear head to toe of just one color. While the Crown Princess Victoria of Sweden looks lovely, the constant hue washes her out.
Like we said, the monochrome thing is very popular at British weddings. However, style veterans like the queen like to mix things up with different textures in like colors.
Listen: There's an apparent hierarchy across the pond. When Queen Elizabeth wears a pastel yellow, you bet Camilia, Duchess of Cornwall is going to wear a more muted pastel. Typically, high-society stylists will ask brands or designers if similar looks were bought from others for the same event.
When it's your wedding, do whatever the heck you want. Wear a Beyoncé-worthy satin coat to shine a little brighter than Kate Middleton if you have to!
We say embrace your sexy, but at traditional British nuptials, dressing conservatively is typically the default, which means hemlines are usually never higher than a few inches above the knee and low necklines are almost never seen.
If you got it, flaunt it. Find a silhouette that's both appropriate for the occasion but will get people noticing, like how Pippa caught everyone's attention at Kate's wedding with a super-toned backside.
