My one and only Balenciaga is my go-to bag for all occasions. Because I have a black city, I don't use it when I wear tans/browns. I know some people like their bag color to 'pop' but even when I wear a lot of black, I feel like my Balenciaga always fits my outfits best.
I probably use my Bal 3-5 times a week, but I do make a conscious effort to rotate bags because I don't like any of them to get ignored.
