For anyone interested, Compass Rose has her bra stashes back in her shop. I just received mine in the mail. It is very well made and it will fit even the largest bra in the front, IMO. Attached to strap and tucked under the side of the bra...I can't even feel it sans cards. I'll try with later. I am not one who keeps my passport in a money belt so this, if I ever use it, will work great for me. Airport to hotel on public transportation is likely the only time I'll use it, but it is great.
I don't often use a money belt, and dislike them. Only this forum makes me think twice. As the leg wallet doesn't work with my wardrobe anymore, this will work well. Again, it's only for cards, which I like.
