If you like thin chamois, you might try REI. My first pair of shorts was their brand and it has pretty thin padding. It is all one piece, thin and fairly wide.
I am still trying to find my comfort zone for the *girly bits* too! I'm trying a terry butterfly saddle (good so far) and I have a pair of Bontrager women's sport shorts that I kind of like...they are nice and long on me (which I like) but the jury is still out on the chamois part-it is sectioned but seamless, with the thicker sections on the sit bone parts. I did a 45 mile ride in them and still had some pinching of the bits, even though I used some chamois cream.
Just not sure yet which combo is right for me.
