One of my chapter reviews sent me searching for articles on how to write inner dialogue (as opposed to narration). For years I've seen and written narration in normal font, 3rd person, past tense, and inner dialogue in italics, 1st person, present tense, and both could appear in the same paragraph together. I thought maybe it was a genre difference between me and my reviewer, but it seems the rules are changing. I also thought that switching to inner dialogue on a limited basis actually gave a deeper POV for those thoughts. According to theeditorsblog (see below), it may be the opposite. I visited several websites that suggest it is increasingly common to lose the italics entirely, yet still switch between 3rd person, past tense and 1st person, present tense in the same paragraph. That would take some getting used to. I think most of my reviewers would flag that as a mess, especially if it came in the middle of a paragraph.

Here's mine using old school formatting (from the viewpoint of another character, Father Romano):
A scowling Father Calabrese stood at the office door, hands on hips. The elderly man wore an ankle-length black cassock, a fascia cinched above the waist, and a full clerical collar. He was the only priest at Orfanotrofio di San Nicola who never stooped to wear the simple uniform of the other priests: black shirt, black pants, and a tabbed collar. Just in case the Pope drops by unannounced, eh?
