你幻想过我们的婚礼会是什么样的么

You've ever imagined how our wedding would be?
Have you ever imagined how our wedding would be?

第一句更口语。很少口语说法里会用到illusion的。

Have you ever imagined how our wedding ceremony would look like ?

Have ever you got the vision of our wedding?

What is it like?

越口语越好。

你幻想过我们的婚礼会是什么样的么?
What kind our wedding of your illusion will be?
