Congrats... stunning bags! I agree, the Kristin is more casual and the Sydney more formal. I actually think the Kristin would be more versatile because I can see it with jeans or a business suit... I'm having a hard time seeing the Sydney with jeans, but it may also be because it is the lizard one. Anyway, I'll stop rambling... gorgeous bags! Keep them both if it's in your budget!Beautiful Bags! The kristin is more casual look while the sydney is more formal. What is your lifestyle....more casual buy kristin, more formal sydney! Hope that helps!
