King Charles is modernizing the monarchy by slimming down the ranks and possibly relaxing dress codes.

Princess Kate may opt for a low-key headpiece for Charles' coronation ceremony, while the king and queen will wear ornate headpieces.

Tiaras were worn by every royal lady at the Queen's coronation in 1953, but times have changed in 70 years.

Royal fashion expert Miranda Holder noted that Kate must not pull focus from the king with her outfit.

Kensington Palace no longer gives out details about Kate's wardrobe.

The increased expectation for Kate to deliver glitz and glam may alter the palace's fashion stance.

Charles is embarrassed when he is put in second place.

Perhaps Kate will dress more subtly so as not to overshadow the monarch.

The decision is still being made, according to sources.
