i am actually thinking of the denim bum bag, i may just throw it around my shoulder/chest and not wear it around my waist, but i love the shape and the casualness of the bag; i have tons of cross body bags including my eva that i love, but sometimes with the kids i just want something real casual...as far as guys go, i see nothing wrong with it, but i know my dh would never wear one...
I don't really like the designer fanny packs (i went through a stage where i really wanted one... thank god i snapped out of it!) I don't think the fact that they are made by a designer makes them any more acceptable.
worn on the shoulder/chest is IMHO an acceptable way of wearing it however im not sure how practical it is.
I just disagree with bum bags/fanny packs, no matter what. The fact that it has a logo on it, doesn't make it any cooler in my opinion. Would you genuinely wear a toilet seat as a hat if it was monogrammed with LV?
