The Chelsea line is very nice, the pebbled and nubuc leathers are great, soft and slouchy. I have had both kinds, it depends on whether you like two handled satchels or single straps hobos. Now knowing my preference (ALI) if I were to choose a Chelsea it would be a hobo. I think the Jocelyn is a great looking bag, its a carly style with a turnlock top flap!
My most favorite Optic is the khaki metallic optic! But be careful if your looking for one on Ebay, the Khaki optic satchel is greatly counterfeited.
