Kan kan bum bag
The bum bags are trendy and Misako has prepared a whole collection that I'm sure you'll love. The Kan Kan waist bag has a funny design with geometric shapes in pastel shades on a raw background.
It has different pockets with zippers so you can have all your things well organized and at hand.
The strap is adjustable so you can wear it crossed or at the waist, as you like.
