How do I write something like this?

[kidcharlemagne]

This is just an example by the way but would it be?

1) I walked into the room and thought to myself, what is he wearing?
2) I walked into the room and thought to myself: What is he wearing?
3) I walked into the room and thought to myself, "What is he wearing?"
4) I walked into the room and thought to myself, 'What is he wearing?'
5) I walked into the room and thought to myself, what is he wearing?

Thanks :)

I'd go with 5), but with a capital: What is he wearing?

[Silent Rob]

I'd agree with Manuel.

[scarletpeaches]

None of them.

"Thought to myself" is tautological.

[Silent Rob]

Oh yeah, good point. Doh!

Just take out the 'to myself' if you want to write it like that.

None of them.

"Thought to myself" is tautological.

Good point, although, as I mentioned, this is not in the MS but just an example. So, to clarify, is this the best way to say this:

1) I walked into the room and thought, What is he wearing?

Or should it be with a period (or a colon????)

2) I walked into the room and thought. What is he wearing?

Mmm...that doesn't look right. Guess it's 1) right?

[Silent Rob]

Right.

I'd say:

I walked into the room. What is he wearing?

or

I walked into the room. What was he wearing?

Reasoning: It's first person, so everything the narrator relays to us is his thoughts. You can either italicize if you want to emphasize and focus on the immediacy of the thought, or just make it part of the narrative.

EDIT: Wait...are you talking about punctuation? Then I'd go with: I walked into the room and thought to myself, What is he wearing?

Viva le colon!

I walked into the room and thought: What is he wearing?!

I'd say:

I walked into the room. What is he wearing?

or

I walked into the room. What was he wearing?
This is what I thought too.

None of the above. Even if the example isn't real, I wouldn't construct it like that. (if you have a real example, that might help us more :D)

To me, it would be more like this:

The smell of homemade cooking filled my nostrils when I stepped through the door. The walls told me this was a nostalgic place filled with old pictures, antiques, and outdated furniture. A coke machine hummed in the corner while people ate their meals and talked about their lives. I scanned the room and found Jack sitting alone in a booth in the back. What was he wearing?

I think that anytime you "walk through a door" in a book, you should probably add some sort of description of the setting. Unless you've already done so previously.

However, I figure that your question was more about what to do with thoughts? The answer is put them in italics and that's it. I don't think you need to tell us that "they thought" something.

None of them.

Note to self:

Scarlet Peaches is right.

When I reached reached the room, I saw him. What the heck? What is he wearing?

Aside from the "to myself" part, any of the options you presented would be fine. It all depends on what you like best. Personally, I italicize my thinking bits of dialogue and use no quotes.

I don't know what the surrounding descriptions are, and by my opinion this sentence can refer to various situations, can be imagined on various ways. Personally I would expand it.

I happily strolled into the hall. Then I saw him. My left eyebrow is slowly raised; caught on the great hook of surprise. Oh-my-God! What is he wearing?

Or something like that. For me the upper five version is a bit dry. Also it's depending from the genre. But I would skip the word "walk". Plus as James mentioned, if you haven't described the surroundings before, try to describe it. Here is another example.

I happily strolled down to the hall, took the steps one by one. Pale moonlight watched me through the large windows and grandfather's clock slow echoing rhythm welcomed. Then under the bright chandelier I saw him. My left eyebrow is slowly raised; caught on the great hook of surprise. Oh-my-God! What is he wearing?

This is just an example by the way but would it be?

1) I walked into the room and thought to myself, what is he wearing?
2) I walked into the room and thought to myself: What is he wearing?
3) I walked into the room and thought to myself, "What is he wearing?"
4) I walked into the room and thought to myself, 'What is he wearing?'
5) I walked into the room and thought to myself, what is he wearing?

Thanks :)

Several are right and it depends on your taste. I'd use 2, 5 or 1 (with a capital What and minus "to myself").

It depends on your style and what works best in context.

More than one way of skinning a cat, right?

Thanks everyone.
