Stylishness rendered in coat or suit common in the States? (5,6)

I believe the answer is:
class action
'suit common in the states?' is the definition.
The definition suggests a singular noun which matches the answer.
'stylishness rendered in coat' is the wordplay.
'stylishness' becomes 'class' (I can't justify this - if you can you should believe this answer much more).
'rendered' is an anagram indicator (letters rendered in a new form).
'in'+'coat'='incoat'
'incoat' is an anagram of 'action'.
'class'+'action'='CLASS ACTION'
'or' acts as a link.
Can you help me to learn more?
(Another definition for class action that I've seen is " This is the case for a lot of people".)
