opinion | fact | age | shape/style | color/design/pattern | nationality | material | noun Example: I've got a beautiful big new long sleeved gray Italian shirt.

Honestly, native speakers will do this intuitively. There is a reasoning behind how we order our adjectives, but there's plenty of information online about the actual order. For example: https://learnenglish.britishcouncil.org/en/english-grammar/adjectives/order-adjectives Something else to note: more than three adjectives before a noun begins to look silly. Just use a couple, put them in the right order and you'll be fine.
