Our favorite royal ladies were busy this year, which means there was a bevy of regal outfits for us to gawk over!
Meghan Markle officially became the Duchess of Sussex in May when she wed Prince Harry, and her royal engagements have taken her everywhere from Ireland to Australia. Kate Middleton was also full of happy news -- welcoming her third child, Prince Louis, in April.
See what the Duchesses donned in 2018 as we round up the standout looks from each.
Here Comes the Bride
We can't kick this list off without talking about Markle's wedding looks. The former actress from L.A. officially became a British royal when she tied the knot with Prince Harry in May at St George's Chapel at Windsor Castle in Berkshire, England. The bride wore an elegant, bespoke bateau neckline dress, designed by Clare Waight Keller of Givenchy.
Change of Dress
The newly married Duchess of Sussex swapped her Givenchy number for a second wedding dress for the reception party later in the day. The stunning halter gown by Stella McCartney suited Markle's modern take on classic style perfectly. A version of this covetable look became available in the designer's first bridal collection in November.
The newly minted royal looked romantic and feminine in a sheer blush pink dress by Ghost and dome hat by Philip Treacy for Prince Charles' 70th Birthday Patronage Celebration at Buckingham Palace in May.
Pretty in Pink
Markle opted for a light pink hue again the following month via an off-the-shoulder Carolina Herrera buttoned dress and matching Philip Treacy hat, similar to the one she wore previously, at the Trooping the Colour -- making the shade her unofficial go-to color.
Out With the Queen
The former Suits star had her first royal engagement with Queen Elizabeth in June. She chose Givenchy again for the occasion -- this time, an ivory caped dress, cinched with a thin leather black belt, styled with matching pointed-toe pumps -- when the duo visited Chester, England.
Chic in Stripes
Middleton and Markle enjoyed a girls' day out at Wimbledon in July. Middleton wore a white polka-dotted dress, while Markle opted for a trouser look via a white wide-leg pant and striped shirt by Ralph Lauren, Altuzarra handbag and Maison Michel fedora.
Bright in Yellow
The Duchess was simply stylish in a sleek canary yellow midi by Brandon Maxwell while attending the Your Commonwealth Youth Challenge reception in London in July. She completed the ensemble with nude pumps and a tight low bun.
Darling in Dior
The Duchess of Sussex was exquisite in a timeless, flawlessly tailored navy blue A-line dress by Dior, featuring her favorite collar-baring bateau neckline at Westminster Abbey to mark the centenary of the Royal Air Force in July. She accessorized with cream-colored pumps and coordinating Stephen Jones fascinator.
The newlyweds visited Dublin, Ireland, in July, and the brunette channeled her inner boss lady in a cropped suit jacket and straight-leg pants from Givenchy and her go-to Sarah Flint leather pumps. The best part? She styled it with a simple white tee underneath.
In the Trenches
We told you she loves blush pink! The royal donned the pale hue again for her visit to the Nelson Mandela Centenary Exhibition at Queen Elizabeth Hall in London in July, rocking a sleeveless trench coat dress by Canadian designer Nonie, finished off with a rose-nude Mulberry bag and Dior pumps.
Markle showed off her toned bare legs in a black, double-breasted tux LBD by Judith & Charles for a gala performance of Hamilton in London in August.
The mom-to-be, who announced her pregnancy upon embarking on a 16-day tour of Australia, New Zealand, Tonga and Fiji in October with Prince Harry, was glowing in the Aussie sunshine. The expectant Duchess wore a striped tied linen dress with a flirty thigh-high slit by Reformation and Sarah Flint brown leather sandals.

A Vision in White
The couple arrived at a state dinner in Nuku'alofa, Tonga, as Markle stunned in a white custom Theia column gown that hugged her growing baby bump, while Prince Harry looked dapper in a classic black suit and bowtie.
The Duchess was especially beautiful in blue during the tour. She took our breath away in a caped gown by SAFiYAA at the state dinner in Suva, Fiji, and in a Veronica Beard shirt dress in Nuku'alofa, Tonga.
Birds of Paradise
Markle's fashion took flight thanks to her dreamy Oscar de la Renta tulle dress with bird motifs. All eyes were on the Duchess as she attended the Australian Geographic Society Awards in Sydney.
Bundled Up in Sweden
Prince William and Kate Middleton, who was pregnant with her third child, Prince Louis, at the time, started the year with a trip to Sweden and Norway in January and February. The Duchess of Cambridge looked ready for cold weather as she walked with her husband and Sweden's Crown Princess Victoria and Prince Daniel, wearing a long buttoned forest green coat with furry black cuffs and collar, topped off with a matching hat.
Princess Diana Vibes
Middleton sported a red houndstooth print double-breasted coat from Catherine Walker while visiting the Karolinska Institutet in Stockholm, Sweden. The bright piece resembled her late mother-in-law, Princess Diana's, Moschino jacket, which she wore in 1990.
A Royal Angel
The brunette radiated in an angelic, cream-colored pleated cape gown with embellished neckline by her go-to designer, Sarah Burton of Alexander McQueen, as she was escorted to a dinner by King Harald V at Norway's Royal Palace in Oslo.
Red Carpet Princess
The Duchess wowed in dark green again at the British Academy Film Awards, two months before giving birth. She arrived in a V-neck, empire-waist dress by Jenny Packham, adorned with glittering emerald jewelry at the Royal Albert Hall in London.
Mint Green Mum
Middleton was all smiles as she headed to the Royal Society of Medicine in London, showing off her growing belly in an adorable mint green bow coat and matching dress by Jenny Packham and Jimmy Choo nude suede pumps, one month before the arrival of Prince Louis.
Mom of Three
The 36-year-old royal and Prince William welcomed their baby boy on April 23. The now-mother of three waved to the crowd outside the Lindo Wing of St Mary's Hospital in London, donning a red dress with lace Peter Pan collar -- another creation by Jenny Packham.
The Duchess of Cambridge was gorgeous in a pale yellow (at first glance, it looks white!) Alexander McQueen coat dress and matching floral hat by Philip Treacy at Meghan Markle and Prince Harry's wedding in May.
In July, Middleton turned heads in a vibrant yellow Dolce & Gabbana frock (similar to Markle's Brandon Maxwell number), complete with romantic fluttery cap sleeves, to watch the Wimbledon matches in London.
For the opening of the V&A Photography Centre at the Victoria & Albert Museum in October, Middleton was super chic in a gray plaid tweed dress with asymmetric neckline by Erdem, finished off with matching maroon belt, Jimmy Choo velvet pumps and clutch.
Fierce in Fuchsia
It was the year of royal weddings! Her Royal Highness donned a fuchsia pink Alexander McQueen knee-length dress, featuring puffed shoulders and a gathered skirt, and a matching veiled Philip Treacy hat for Princess Eugenie's nuptials in October.
The Duchess looked like a fairy tale princess in an icy blue ruched Alexander McQueen gown, further elevated by the Lover's Knot pearl tiara -- the exact one Princess Diana wore -- with teardrop earrings and a pearl and diamond necklace at a state dinner in Buckingham Palace in October.
She Recycles Again!
The Duchess of shopping her closet re-wore a turquoise blue, pleated, square-neck dress by Emilia Wickstead in November on her way to the BBC with Prince William to raise awareness about cyberbullying. She previously wore the frock with a matching hat during her 2014 Australia and New Zealand royal tour.
Matching in Burgundy
The royal sisters-in-law coincidentally both chose burgundy on the same day in November! Middleton visited the UCL Developmental Neuroscience Lab in a Paule Ka skirt suit with a black turtleneck sweater and ribbon in her hair. Markle chose a Club Monaco coat and dress en route to the Hubb Community Kitchen in West London.
