There are a few reasons to engage in this type of consumer indulgence. Repeat purchases are smart buys if you find something that fits you perfectly, or if you fall in love with a piece that will transcend trends but perhaps not last forever. Shoes are a good example. Lots of people have bought and rebought their favorite pair of sneakers or their comfiest ballerina flats. While soles can be replaced with the help of a capable cobbler, certain shoe uppers just aren't able to last forever and continue to look great. You can only polish for so long.

Items in multiple colors or colorways will add versatility to an otherwise safe wardrobe. When I develop an ensemble that I really like to wear, changing the color of a component piece enables me to repeat it more often without becoming bored. I have the same cashmere boyfriend cardigans by Cece in six different colors. Over the last few seasons, I picked up my favorite Marc by Marc Jacobs dresses in multiple colorways when they've popped up on sale.
When I found good deals on merino wool Design History cardigans at TJ Maxx, I bought them in three colors. I also do this with tshirts and corduroy pants. The American Apparel deep V in 50/50 blend and the JCrew Matchstick cords come to mind. Staple pieces like these see a lot of wear. They are able to last longer and stay nicer if I have a few in the rotation.
