There's a costume that I really like called "Bloodthorn Disguise" it's a low level costume. Anyways I notice that it changes appearance almost every time I either exit the game and log back in or zone in an instance.

I prefer it having the fullly/dress covered look with the boots but when I zone in an instance it changes in many different ways but makes it look ugly.

Sometimes it'll keep the look but give me sandals instead of shoes.

Sometimes the dark boots will change into a white colored boot.

Sometimes it'll change into a shirt and hood and the dress part is removed to show my leg armor.

Sometimes instead of fully covered in the chest area it'll change into a short sleeve.

Is there a way to keep it how I like it? Is this a bug or working like it should? I like the way I like it not all these constant different changes all the time, that's why I chose this costume but if it keeps changing into all these random different designs I would rather not wear it at all.
