Oh yeah many brands hold onto their value very well, which is awesome. For me they don't fall under the category of investment, though; they don't make any money while they sit in my closet, for one, and even when I see bags sold at a profit, they seldom reach the returns that other investments do. For example, my stock in a certain credit card company has more than tripled in value since 2011, and my stock in a tech company named for a fruit has more than doubled, which is simply not going to happen with a handbag (naturally, not all stock performs so well, but if you do your research it's not hard to make decent returns.)
I consider a luxury handbag more like a car than like real estate in that respect. Of course, with the way handbag prices keep on rising, certainly you can save money by buying sooner rather than later, and the price increases help the bag retain its value if you plan on selling it down the road. Unfortunately, wearing an item frequently makes it lose its resale value more quickly (because the condition deteriorates with use, and condition is crucial in the second hand market), and as I try to buy only things that I love and thus will use a great deal, I personally will probably not be making any money in reselling my bags, meaning they are terrible investments for me.
