I'd add this
* Store shoes/accessories/hats/etc in boxes and bins and place them at the bottom of your wardrobe if you had that space available.
*organize your clothes per color or per category or both, you might want to have a gradient of color going through your wardrobe from one end to the other, or you might prefer to have a gradient of jacket colors on one side and then blouses, pants, and so on.
*Add baskets/bins on top of your closet if you had that space available for storing out-of-season items or- if planning a new closet- plan to have floor to ceiling built-in wardrobes, if you can afford them, the extra storage space that you get on top of your regular storage is priceless.
*For all of those drawers separators & organizers, closet organizers, shoes closet hangers, etc in Doha, visit IKEA they are ultimately the best
