With the Vera Bradley 60% sale I purchased the Miller bag (been eyeing that style for a while). I purchased this bag for our June trip to the World. My question is - Has anyone ever used this bag as their "personal item" carry on? I'm flying Continental and we are allowed one piece of luggage and one personal item for carry on - and I'm really afraid the Miller might be over-sized for the 'personal' item. Thouhgts anyone??? Am I going to have to return this to my Vera store? Thanks!
