I finally got my shawl a few months ago. All I have to say is be very, very patient. It's about as frustrating as the halfling mask. If I remember correctly, the only mobs that drop the shawl now are the princesses which are an uncommon spawn, but multiple can be up at the same time.
If you can not quickly rip though these by yourself, I would suggest getting a nice group together and go for experience. Just be patient, you might get it in the first spawn or might take several weeks as it took me.
Just so you realize how un-common they are, I got 7 Sargasso Spears (http://everquest.allakhazam.com/db/item.html?item=23746) and about 200k in tribute with Netted Kelp armor and other uncommon drops also while I was doing this. The Spears are lore and do not drop all that often even though Alla says they are common (gotta gate out each time and put in bank and on alts). I sold each for 45k-60k in the bazaar, the stats stink but they are one of the few that proc Snare. Long story short, you can make a lot of money while camping this illusion item.
