Meghan – who married Prince Harry in May – was praised as a style icon with the so-called Meghan effect, seeing real fans copying their clothes.
However, the style of the Duchess was not perfect, with the future mother making the occasional faux pas of fashion.
In August, Meghan came out in her black lace bra showing the paparazzi an unexpected glimpse of the royal neckline as she watched the wedding of Harry's childhood friend Charlie Van Straubenzee.
Meghan wore a beautiful Club Monaco dress, which had a pleated skirt and a belt around her waist.
But the top buttons of the dress seemed to be undone, which meant that her bra could be seen in a big style mistake.
The 37-year-old singer was unaware of the wardrobe malfunction as she smiled and waved at the wedding photographers.
And during the Duchess's British Community tour with Harry last month, Meghan often changed her clothes several times a day.
But the 37-year-old forgot to remove the etiquette of one of their dresses, arriving in Tonga with the label clearly hanging on the clothes.
Meghan looked dazzling in the red dress of Self Portrait in a nod to the country's flag, but all eyes were on the mark that was clearly visible in the hem of her dress.
The mother-to-be involuntarily made another fashion mistake when she chose to wear a semi-transparent dress while on a walk in Fraser Island, Australia, which also featured a bold thigh-high split.
The Reform dress seemed to be transparent in the light, revealing Meghan's pins.
In March, Meghan and Harry made an appearance in Birmingham for a royal engagement two months before their wedding in Windsor.
Meghan wore a long navy blue jacket from J. Crew for the ride, but the spectators could not help noticing the white cross sewn on the back of the jacket.
The tack point on Meghan's coat should have been removed before the item was used.
AND Meghan's wedding dress is said to have surprised the queen like the ex-actress dressed in white, despite being her second marriage.
But not all is bad news for Meghan, who ranked third on the list of the most powerful fashion influencers on the Lyst shopping site.
Kate, Duchess of Cambridge, appeared at number 16, after reaching fifth place in 2017.
