I do own other brands of handbags besides Louis Vuitton and regularly use them in my rotation... They are mainly Coach, with a bit of Marc Jacobs and Balenciaga thrown in.
I used to have a collection that was primarily comprised of Balenciaga bags and then found that Louis Vuitton bags seemed to just fit my lifestyle better after having kids. I try to keep my handbag collection at a "moderate" level and sell things that I'm not using to fund new things. So what you see that is still in my collection are what I consider "keepers" at the moment!
