I'm 5' 9.5" also with a 33" inseam and long arms. I started with a mens Specialized Allez, which was too long in the top tube. Realizing this, I started looking at measurements of bikes before going to the LBS.

What I found out, is that a WSB would not work for me because the seat tube would be too short. Apparently, they really aren't designed for taller women. To make matters worse, most mens bikes were too long in the top tube.

I ended up with a Kuota Kharma, size 57. There's only about a 1 cm difference between the top tube & seat tube, which works for me. I'm sure there were other brands that would have worked, but this one seemed to be a perfect match and it was on sale! It's a really cool color, too.

Just my .02
