What do you think of the size differences? The biggest bag style I like is the Neverfull MM (sold my GM, hated the oversized look on me). I also hear amazing things about the buttery soft lambskin, but I’m leaning towards the wrinkly version ( I feel it’s less shiny- and it’s description is Matte on the YSL site). I would go for the small bag if it’s a good daily use handbag, I don’t overpack my bags, but I do have a toddler so I would need a water bottle and his medication. Thoughts on sizes and material?
