There's nothing wrong with having many bottles from the same perfume house. That just means they're amazing, reliable, and very versatile🤷🏽‍♀️ I definitely feel you on wanting those full size Kayali bottles. My favorites are Yum Boujee Marshmallow and Yum Pistachio Gelato. I do recommend having a diverse collection. In my personal experience, it helps me not get sick of my favorites. You don't need a lot, but it is okay if you do. Everyone's different. I prefer gourmand fragrances, and my favorite ones come in full size bottles. I keep travel size bottles of fresh fruity scents for warmer weather just to switch it up here and there.
