We adore Kate Middleton, 35, for many reasons. The commoner, who was conferred the title the Duchess of Cambridge when she married to Prince William, 35, is hands-down the most down-to-earth and relatable royal out there.

Indeed, she is a no nonsense mum of two who never hesitates to put her peewees, Princess Charlotte, 2, and Prince George, 4, in their place. Even if it means managing their tantrums in public.

Above all, what women love most about demure Kate is her effortless charm and polished style. In a world of over-the-top styles and half-naked celebrities, her smart sartorial choices are testament to her elegant, yet glamorous ethos. This is especially evident when it comes to her maternity style.

Now that she’s expecting her third child, who is due in April 2018, the Duchess continues to wow us with her wardrobe picks. How does she manage to step out looking so put together? We examine her top maternity fashion moments.

#1 The time she broke with tradition

When: 17 March 2015
Then pregnant with Princess Charlotte, the Duchess decided against wearing green to mark St Patrick’s Day, dressing her bump in a brown Catherine Walker coat instead. She did, however, pay tribute to the Irish feast day by pinning a gold shamrock brooch on it. The brunette also swapped her signature cascading waves for a chic updo and completed her look with a Lock & Co hat and simple gold drop earrings. (Photo: PopSugar)

#2 The time she flaunted her pregnancy curves in a high-waist dress

When: 4 June 2013

Not one to allow her bump to get in the way of a good party, a heavily pregnant Kate is literally glowing in her Jenny Packham dress and matching long jacket to celebrate the 60th anniversary of Queen Elizabeth's coronation. Just weeks away from giving birth to Prince George, the first-time mum-to-be tops the blush-coloured ensemble with a Jane Taylor hat. (Photo: The Indian Express)

#3 The time she rocked a leopard-print dress

When: 13 June 2013

Whoever said Kate doesn’t know how to experiment with her looks obviously missed out on this roaring number. At the Princess Cruises ship-naming ceremony, the normally understated Duchess attends the ceremony in a flattering Hobbs animal-print dress. To balance the bold look, Kate keeps accessories to a minimum ― pearl drop earrings, a black fascinator, chocolate-brown pumps and a white clutch. (Photo: Pinterest)

#4 The time she got whimsical in a polka-dot dress

When: 26 April 2013

Make no mistake, Her Royal Highness does not only sashay around in high-end labels, she’s also a high-street girl at heart. At the opening of the Warner Bros Studios in Leavesden, England, Kate leaves everyone spellbound as she debuts her first-ever maternity look in a Topshop polka-dot dress topped with a cropped Ralph Lauren jacket. Here she’s pictured casting spells alongside her husband and brother-in-law, Prince Harry. (Photo: The Huffington Post)

#5 The time she dazzled in an icy-blue number

When: 24 April 2013

Normally pictured in conservative outfits, it was refreshing to see the Duchess switch her style up a bit for the National Portrait Gallery reception. Kate, then 6 months pregnant, stepped out in a fun, sparkly baby blue Emilia Wickstead cocktail dress and what are rumoured to be her favourite pair of grey suede heels. (Photo: www.etonline.com)

#6 The time she wasn’t afraid to show some skin

When: 23 October 2014

After being out of the limelight because she was dealing with hypermesis gravidarum ― acute morning sickness ― Kate turned heads in an unforgettable black Temperley London flare dress while attending the Action on Addiction Autumn Gala. Although she flaunted cut-out panels that exposed a nude slip, the Duchess still managed to keep it classy, pulling her bold look together with an embellished clutch, glam pendant earrings and lots of confidence. The Kate Middleton effect was especially strong with this number as the dress sold out within a day! (Photo: www.elle.com)

#7 The time she showed the world how versatile wrap dresses are

When: 19 February 2013

Sporting a modest second trimester bump, Kate arrived at Hope House ― a safehouse for women recovering from substance dependence ― in a summery black-and-white Max Mara Studio wrap dress. The universally flattering dress had everything going for it, including a tie that cinched in her waist and a v-neckline that made the most of her cleavage, while making her face look sharper.

#8 The time she let her coat do all the talking

When: 21 April 2013

While the Duchess is a big fan of coats and wears them frequently, if we had to pick our favourite, it would have to be the time she wore a Mulberry mint-green coat dress for a parade in London. Trimmed with gold flower-shaped buttons, the pastel-coloured number was further accentuated with a light brown Whiteley fascinator and her favourite nude LK Bennett pumps.

#9 The time she brought canary yellow back in style

When: 22 May 2013

When invited to a garden party, an 8-month pregnant Kate decides to ring in the festivities in a canary yellow Emilia Wickstead frock. Staying true to her “go bold or go home” mantra, the Duchess set off her vibrant look with a classic cream-coloured Jane Corbett fascinator, pearl drop earrings, nude pumps and matching clutch.

#10 The time she looked like a Disney princess

When: 24 November 2017

Kate looked every inch the princess when she attended the Palladium Theatre’s Royal Variety Performance in a full-length glittery Jenny Packham gown and sparkly stilettos. The glacier-blue number, which showcased her just-visible baby bump, had a sheer overlay encrusted with in sparkly sequins and crystal flowers. Many noted the whimsical resemblance the dress has to Princess Elsa’s signature outfit in the Disney animated movie Frozen. Needless to say, netizens went gaga over the look and a quest to find the closest replica is in full swing. (Photo: www.bravotv.com)
