Outfit With Oversized Sweater,Scarf and Shades. The large clutch (?) bag, shades and hat have this looking like a very intentional statement as opposed to a warm winter 'throw-on' outfit. Did you notice the hand gloves match the scarf?
It's an old long sleeved shirt that is turned into a skirt. It is useful for when you don't have a skirt that matches your outfit or you just don't have any at all and you have an old sweater that you don't wear anymore and you want to make use of it.
