Okay, I finally finished the Quest a Pose by any other Name.
I activated it awhile ago, but because I was a redmage below level 8 and I did not want to buy a tunic at the time, I put it off until I could get one. Finished it today.
The biggest tip is to make sure you have the item with you that you will need to wear. It is different by job, so look it up to see. For mages you need the basic tunic. I also unequiped all weapons before I changed into the tunic.
You talk to Angelina, then wait and talk to her again, she will tell you what to wear and then change into it. If you change into it too fast, before the second conversation you deactivate the quest, and you have to start all over, by zoning.
Then wait a few seconds, change into the tunic, and talk to her again. Place the painting in your moghouse. I don't know what the key item is for, but I am sure it comes into play sometime.
