I have a very similarly sized closet that I share with my husband. I have a few tricks.
Inside, against the "end" wall at the other end away from the door, I have a shoe organizer, something like this, but with one more tier (i.e., the shelf is perpendicular to the main wall).

I use a bar that hangs off of the bar with jackets and sweaters on top and blouses below.

I also made my own peg board that has both hooks (for pj's) and wooden pegs (for belts, necklaces), in two offset rows. The board is attached to the backside of the bedroom wall.

I also keep my wardrobe to a minimum! (And rotate out summer/winter clothes and shoes)
Good luck.
