I know this has been asked MILLIONS of times, and I apologize in advance.....For those of you that have or plan on carrying on your dress, are you bringing some sort of personal item too?I am going to carry on my dress, but I was also going to bring a small back pack to carry on my camera & lenses (I refuse to check them) Do you think this will be ok to be considered my "personal item" or vice versa (back pack as carry on and dress as personal item)?TIA!
