I buy spares of a lot of things. I wear dresses all the time but I only enjoy a certain cut. So when I find a dress I love with the right cut, I almost always buy it twice because it’s guaranteed I’ll wear it several times a week, for however long it takes for it to wear down. Same with shoes. My feet are problematic so when I finally find shoes I like, you bet I’m getting them at least twice. I tend to wear the same shoes every single day so they usually only last a year until they fall apart. By that time the shoes I loved are not sold anymore. But guess what! I have a brand new pair in my closet for that exact reason.
