How do you justify choosing nylon over leather?

I have the Prada diaper bag. I bought it when I was first pregnant 8 years ago (time flew!) I use it almost every weekend when I’m shuttling my kids from place to place. It’s lightweight, holds what I need, still looks great, has just another “logo” to be designer but still not in your face, and I feel chic carrying it. I love the style and for me, it has 100 % been worth it
