Hello,

I wonder how the words are used.
In 'Useful English', there is a sentence : 그 여자가 입고 있는 명품이 다 진짜일까?
Teacher said the answer was "Do you think the clothes she is wearing is all real?".
Can I use the words like 'authentic' or 'genuine', instead of 'real'?
What are differences in the use of those three words?

Thank you.
