Amal Clooney and husband George at the Royal Wedding

Even amongst the star-studded Royal Wedding guest list, Amal Clooney in Stella McCartney was a welcome ray of sunshine.

Eternally elegant, the human rights lawyer brightened up the style stakes - literally and figuratively - in her tailored-to-perfection yellow frock.   

It looks like yellow ain’t so mellow anymore as Mrs. Clooney evidently captured the imagination of wedding guests the world over. According to Lyst, once she stepped foot in Windsor Castle, there were over 17,000 online searches for her Stella McCartney number.

Unfortunately, the dress isn’t available to mere mortals yet - such are the perks of being an international powerhouse.

The mother-of-two rarely puts a foot wrong with her sartorial choices. While you can’t get your hands on her exact look, take a leaf out of her book and get a head start on searching for the sunniest shades in time for sending out your summer RSVPs.

People just won’t stop getting married, and so the hunt for ideal wedding guest dresses remains omnipresent. There’s only so much lace, ruffles and peplums that we can handle, but thanks to Amal we’ve been reminded that even opting for a hue that’s outside of your usual comfort zone can up the ante entirely.  

Whether your go-to look is chic, classic, contemporary, or cutting-edge: here are citrus styles to suit all tastebuds. 

For the Good Girl 

The wedding guest who does what she's told, dutifully brings a pair of flat sandals for the end of the night, and doesn't go to ape at the free bar. This ankle-length straw dress is like a chilled glass of Sancerre: safe, light, delicate, and reliable.

For the Scene Stealer

There's always a guest with an air of mystery at a wedding: maybe she went to college with the bride and her tousled hair holds all their secrets, or perhaps they met in the bathroom of a nightclub and struck up a random friendship. Either way, this guest shows up nonchalantly and commands everyone's attention with her je ne sais quoi ways.

Whether you're an enigma or not, keep them guessing as to who you are with a dress that toes the line between sexy and sweet.

For the Queen of Quirk

For some wedding guests, the notion of formal dressing and fascinators is enough to send them into a cold sweat. Luckily, the rulebook isn't as black and white as it once was. Mini-dresses and sparkly details are now just as acceptable as monochrome and mid-length.

We dig the idea of pairing an after-hours embellished party dress with contrasting, statement accessories to keep things unconventional.

Sequin Embellished Dress€291, Aniye By

For the Dance Floor Diva 

When it comes to this guest, the speeches are doldrum and the cutting of the cake is a bore. She lives for the newlyweds' first dance to be over so she can have her own moment in the spotlight.

Texture is key, as she sets about shaking her tail feathers. Ruffles, fringe, tassels, or any additional fabric that creates a great sense movement is a golden choice.

Lorena Dress in Mustard€79.95, Folkster

For the Boho Babe

Nothing grinds our gears more than the guest who rocks up in the dress you've been dreaming of and claims "Oh this? It's vintage". 

We all deserve an authentic, flowing maxi from the 1970s, but life doesn't work that way. Stop crying helplessly into the racks of second-hand clothing stores and consider these frocks your cheat sheet to sartorial success.

Floral Print Cold-Shoulder Gown€350, Self Portrait 

Kaya Dress€691, Marissa Webb

For the Minimalist Maven

Weddings are ten-a-penny for this guest, who has long since realised that investing in simple, classic styles means she will always be prepared for formal affairs. 

Swap out the earrings, jazz it up with a clutch, and let the shoes do the talking. These are good gúnas to have on deck.
