My preference is for hand- or arm- bags, and I really do like carrying them at the elbow; there's a 'pocketbooky' vibe I enjoy. I have shoulder bags too, but the strap(s) must be just long enough to 'swing' the bag onto the shoulder one-handed--and not so long that the bag swings loose. There's nothing more annoying than having a bag thudding against your hip! (Well, maybe a few other things . . .) I've never been comfortable with the cross-body, 'messenger' style, although I totally understand its utility. I guess it's a case of form over function for me!
