You can wear white
Can guests wear white to a wedding? According to Kate they can! Duchess Catherine has worn white to multiple weddings, but she ensures she doesn't steal attention from the bride by choosing patterned dresses. Kate, while pregnant with Prince George, wore this polka dot dress from Topshop, to a friends’ wedding in Oxfordshire. The polka dots and the black accessories added enough colour and pattern to her outfit to make it perfectly appropriate.

And black is fine, too
It used to be seen as a bad omen to wear black to a wedding, but Kate proves that it’s actually a sleek and modern look for guests. Shortly after William and Kate's engagement, the soon-to-be newlyweds attended the wedding of close friends Sarah and Harry. Kate looked regal in an Issa dress (which she first wrote to William’s cousin Peter’s wedding) and a velvet coat from Libelula. All black can be a bit dower for such a happy occasion, so Kate brightened her look with colourful accessories—purple shoes and clutch in luxe velvet.

Shop your closet
You don’t need to buy a new dress for that upcoming wedding, instead take a cue from Kate and shop your closet (though her closet is arguably quite a bit bigger than yours –sorry!). For the wedding of Princess Diana’s niece in 2012, Kate paired a Jenny Packham dress she first wore in 2011 on the royal tour in California with a silk Katherine Hooker coat she premiered at the Order of the Garter ceremonies in the same year. Kate makes her repeated outfits look brand new by switching up the accessories. She swapped a pair of sandals for classic pumps and added drop pearls instead of studs.

Get a blowout
When Kate gets a wedding invitation in the mail, she knows exactly how she will wear her hair – in her signature blowout. Kate’s bouncy curls (sometimes pulled back in a half-updo) pair perfectly with every fascinator and cocktail hat in her large millinery collection. Shortly after her own nuptials, Kate attended the wedding of Sam and Annabel in a Zara dress and a bold Lock and Co hat. Her hair, as always, looked amazing.
Don’t buy new shoes
A wedding and a night of dancing is not the place to break in a pair of new shoes. When Kate knows, she’s going to be on her feet all day, she breaks out her trusted L.K. Bennett heels. She’s worn them for multiple royal engagements, royal tours and, of course, weddings. For the wedding of William’s cousin Zara to her rugby-playing fiancée Mike, Kate looked understated in an all cream outfit, including her comfy court shoes.
Lace is always good
When in doubt, wear lace. Duchess Kate has an enviable collection of lace dresses, which she tends to break them out for weddings. At the wedding of her childhood pal, Kate repeated the navy Erdem shift dress she first wore when she arrived in Ottawa for 2011’s royal tour. She added a bolero jacket, gold-plated belt and navy accessories, making for a romantic wedding look.
