I love Chanel and Balenciaga, too. IMHO, talking about 2 different worlds here. I mostly use my Chanel during formal or dressy occassions and if I want to make a statement. My Balenciaga when I am in casual and the mood is relaxed. I believe I can't go to a wedding in a Bbag. Fake Chanels are everywhere, yes, because it is a more sought after bag in the market. Bbag ideally is for the people on the GO, chic, hippie looks and seen more on the young generation who can easily afford them. Chanel prices is double compared to Balenciaga. I can always buy two Bbags on the value of one Chanel flap.
It is a matter of two opposite poles which is justifiable.
