The best belt is a personal preference, but here are my thoughts. My husband strongly recommends the hidden pocket. There are no waist straps since it hangs from the belt, inside the pants. It feels comfortable, is not obvious from the outside, and he doesn't even feel it. RS, Eagle Creek, and other travel stores carry them.
I have had less success finding one that works for me. Most money belts don't seem to fit a woman's figure very well. With the waist style, I don't like the strap around my waist and the pouch adds a layer to the belly which is unattractive and uncomfortable for me. You really need waist-high pants, too. Some recommend turning the pouch so it lays on the small of the back, but I tend to perspire there. A plastic bag protects the contents, but I still have a clammy feeling plus still have that strap on the waist.
I tried the hidden pocket; it's not bad when standing up, but when sitting it bends at the wrong place, is uncomfortable, and noticeable. I don't wear a belt so had to safety pin it inside my waistband, and I didn't feel really secure with that. It may fit a man perfectly, but it hung down too long on me and moved around when I walked, sometimes to the outside of my leg and sometimes slipping almost between them. I was constantly fidgeting with it, which must have looked odd.
Neck pouches are obvious when wearing a thin knit top, especially with smaller women. Some people wear them more under the arm than in front, but I find that sweaty and uncomfortable. Someone recommended pinning items into your bra, but many women don't have enough bra to accommodate that, plus you have the comfort/perspiration issue.
I know someone who uses an ankle pouch for extra money and credit cards, but she always wears long pants. This won't work for capris or skirts, and won't hold a passport.
So I'm still looking. Sorry I can't recomend one for women, but maybe this will at least help you to eliminate something.
