Reignbow! She's worn every colour under the sun in her record reign - and knows every fashion trick in the book. Here we present the ultimate guide to the Queen's style

Unrivalled: She is Britain’s ultimate fashion icon — utterly majestic from the crown of her hat to the tips of her patent shoes

Red white and blue: In the 63 years and 219 days the Queen has reigned, she hasn’t put a foot wrong when it comes to her wardrobe, which is impressive, considering she changes outfits up to five times a day

Royal yellow: Some have claimed the Queen doesn’t care about fashion. But a closer look reveals the opposite

Full of youth: As Angela Kelly, her dresser for 21 years, says: ‘The Queen loves clothes and is a real expert on fabrics. It’s not been me teaching the Queen — it’s the other way round.’ Here she wears a tight-fitting dress to a garden party in Sydney in 1954

Royal wave: In her youth, Her Majesty often wore eye-catching designs, from turbans and opulent furs to short-sleeved dresses cinched at the waist. It's now been 43 years since she exposed her upper arms

Lady in red: You will spot not a hair out of place, a wrinkle in the fabric of her outfit; no dropped hemlines, visible hat pins or scuffs on her heels, Left, she visits Kew in red. Right, is the Queen and Duke of Edinburgh on the Great Wall of China in October 1986

Picture of decorum: Here she dulls down in grey to observe a two minute silence at the Sandringham War Memorial in Norfolk to mark the 90th Anniversary of the Gallipoli campaign

Polka dots: The Queen’s favourite pattern is polka dots, making up 20 per cent of her wardrobe. She has spotted hats, skirts and dresses in almost every shade under the sun.

Clever tailoring: When you see the Queen wearing an open coat with what looks like her dress visible underneath, it’s not as it seems. Angela Kelly inserts fabric identical to the dress across the front of the coat to give the illusion of it sitting open without exposing her to a gust of wind

Keep your hat on: The heads of her hatpins are covered in the same fabric as the hat, to make them almost invisible. Every outfit — apart from evening gowns — is fitted with pleats, so the skirt doesn’t rise when she sits or walks up stairs. Knife pleats (straight lines), kick pleats (fanned) and box pleats (wide folds) are used, as well as zips at the back so clothes can be changed quickly.

Striking a pose: The queen strikes a similar pose in 2011, left, and 2012, right, but the attire is very different. Only the black patent bag and trademark shoes remain the same

Important company: The Queen stands with Pope John Paul, left, in green, in 1982. Right, she meets Federal President Walter Scheel on a state visit to West Germany in 1978

Elegance: According to Stewart Parvin, the Queen’s favourite couturier, she prefers dresses over skirts, as they won’t become untucked. All her gowns flare out from the hip or knee to make them easy to move around in

Single or double? Her single-breasted jackets all have an uneven number of buttons (usually one or five) while double-breasted coats tend to have eight. Though she wears capes for formal occasions, she has only been spotted wearing one from her own wardrobe once, in 1984 at the polo
