Fashion rules the Royal Family must obey
Colourful coats

Queen Elizabeth was often seen with bright coats and matching hats.
Official outings

For official outings, women usually opt for dresses and men for suits.
Smart casual

Even on informal outings, royals must look put-together. That does not exempt men from wearing collared shirts.
Ladies' coats

Women's coats should be a minimum of knee-length.
Hats on!

For official events, ladies always wear a hat.
Tiaras

After 6 pm, hats are not to be worn indoors. It's tiara time!

Unmarried royal women do not wear tiaras on any occasion.
All-black essential

All royals pack an all-black outfit when they travel.

This is in case of an unexpected funeral.
Neat hair

Kate Middleton is said to have her hair blow-dried at least three times a week to maintain her groomed long locks.
Gloves

Kate Middleton only wears gloves when it is cold. The Duchess usually greets people with bare hands.
Military uniform

It is also common for royal men who serve in the military to wear their uniform to their wedding ceremony.
Boys dress code

Even in pyjamas, the young Prince George looks smart and put-together.
Girls dress code

You will never see the young royal in glitter.
Family affair

This is particularly true for formal events.
Manicure

Nails are cut short and natural or painted a neutral tone.
Clutch

This is said to be to occupy her hands and prevent unwanted handshakes. Royals are always the ones to initiate a handshake.
