Adjectives are usually placed either before a noun (as part of the noun phrase) or after a noun, pronoun or verb. The rules for this placement are quite simple, but when we use more than one adjective the word order is important, to sound more natural and to make the meaning clear.

A disgusting pink plastic ornament. [opinion – color – material]
She was a beautiful, tall, thin, young, black-haired, Scottish woman. [opinion - size - physical quality - age - colour - origin]
