Everything goes into my Michael Kors Tote, it is the perfect size.
Like my iPad, I have to have my iPhone (Yes I am an Apple lover). My iPhone case has turned more into a wallet as I usually have my iPhone out, but this is a great wallet as it fits a ton so stuff.
The best little mirror, brush combo and of course my bathing suit, just in case I were ever to loose my luggage at least I know I can wait for it while laying on the beach!
And lastly but most important, those planes are cold!! I always bring a pashmina with me, doubles as a blanket as well.
