Oh wow, I think I would get totally lost :D I don´t believe that all girls need to carry so many stuff to feel secure...
I always prefer not using any bag since it is much more comfortable. When I go out for dinner or a party then I use a small one to store my phone, keys and lipstick. That´s it :)
You are certainly very confident !
Or it´s just that I refuse wearing make-up :)
