If you have a more womanly torso and leg configuration, the womens suits will probably still fit better.

Did you try the TriSports Wetsuit Calculator Thingy? http://www.trisports.com/wetsuits.html - it's not super exhaustive but might help you narrow it down. I put in "Wide Shoulders & Narrow Hips" with some other basic weight/height stuff (average) and it recommended 2XU and Zoot. (I don't know if it checks Aquaman and Profile Design, I don't know if they stock them - definitely won't check Xterra since they distribute differently)

I have a 2XU suit and it was one of the few that I felt wasn't too long in the torso for me. I do not have narrow shoulders, probably average to broad, but I do have breasts. I feel like the 2XU and Zoot suits have more give in the neck than the Xterra and Blue Seventy suits I've tried on, maybe that's a factor of the shoulders not being broad, never thought about it that way. The 2XU suit fits snugly around my hips and is harder for me to zip up than some others, so I think it is more of a narrow shape (could just be a function of having to size down in order for it not to be too long overall).

You might call one of those places that sells a lot of variety (and even TE) and chat with them specifically, many of them do rentals or size enough people that hopefully they can help - even if it's to narrow them down.
