Wallpaper Help

Just wondering if any of you smart and savvy bloggers have any suggestions on where to get some cool wallpaper for my dressing room?  I'm open to purchasing online and really only have one wall to cover, so I don't think I'd need to order too much.

As mentioned in an earlier post, I'd love something bold and graphic, and it could be girly if that worked, and I'd like it to work with lavender walls.

Suggestions? I'd certainly appreciate it!!
