Designer Bags

If you had to choose your first designer bag what would it be and why? I’m a mom of 4 and my hubby always wanted to buy me a designer bag but I say no because I carry a backpack with all the essentials for my babies and also because they’re so dang expensive but now I’m coming around to it and would like to hear ppls opinion on which Bag they would get and why. Louis Vuitton, YSL, GUCCI and so on
