Queen Elizabeth II may have the most difficult-working wardrobe on the planet.

The Mail wrote Sunday, February 15, 2015, that "every outfit worn in public is carefully calibrated in order to inspire or remind, signal gratitude or respect to convey a feeling of power or familiarity." "Her Majesty does not set trends or follow them -- but she is deafened to the call of fashion. She has her own unique style."

The queen's fashion choices include tiaras and Hermes scarves as well as hats and Hermes scarves. She also owns Launer London handbags as well as umbrellas.

The queen is now well-known for her bright coats that allow her to be seen by large crowds. In earlier decades, she was a young princess and monarch.

Here are some highlights from the Queen's style throughout the years

HER CHILDHOOD

Wool or cotton? The queen's birth has sparked style debates, writes Bethan Holt (fashion editor at The Telegraph, and author of "The Queen: 70 years of Majestic Style").

From the beginning, her wardrobe was a national obsession. She had a layette made by her grandmother and mother, with some help from women from low-income backgrounds in Britain. Lilibet's mother, the Duchess, was adamant that wool babies looked like "little Gnomes". She opted for frilly cotton and rejected anything too fussy.

Four years later, sister Margaret arrived and the sisters often wore identical clothes into their teens. Marion Crawford, Marion Crawford's former governess, said that the future queen was a girl who "never cared a bit" about clothes.

Crawford's controversial memoir "The Little Princesses" stated that "She wore whatever she was told without any argument."

THE YOUNG HEIRESS

After the turbulent abdication of her uncle, and the rise to power of her father, King George VI, Princess Elizabeth was made heiress presumptive (absent any male heirs, which never happened).

According to Holt, Norman Hartnell is the couturier. Although there were many other designers, Hartnell was responsible for dressing the family, including the princesses aged 11 and 6. Holt wrote that their "bow-adorned dresses, little cloaks signaled a return to calm dependability of monarchy."

Elizabeth, 18, began making more public appearances during World War II. She was a mechanic at the time and trained in the early 1950s. Holt says that it was the only occasion she wore pants (or boiler suits) regularly.
