grammar - Correct tense for "I wish I had worn socks today"

I had an argument in the office today, about structuring something I said about not wearing socks.
I said the first of the four lines below, then everyone had their input. All the arguing gave three more options. What is the correct way to say this?

I wish I had worn socks today.
I wish I'd worn socks today.
I wish I'd had worn socks today.
I wish I'd have had worn socks today.

Answer

Answers 1 and 2 are identical (apart from I had being contracted) and are correct.

The rest of them are not.

Also note that a that has been elided from all of them. The full sentence would be:

I wish that I had worn socks today.
