My avatar is dressed like this because of the day.
It is: Chrismas Eve, the 11th month anniversary of 'dating' my beloved, and the deathday of my best friend's cat.
The latter 2 both have major emotional effects on me, so my avatar is a combination of greif, sorrow, love, hope, and feelings of anguished suppression that come with both.
The first of the events just means that most of my Christian friends are busy today. My bff (the one greiving her cat) is here at my house right now though.
I would have done all black for mourning, but I wear black all the time virtually and RL, so it wouldn't mean anything. My avatar is dressed instead in white, which is almost never prominently displayed on me.
It also stands upon a cloud, to represent the cat in heaven now.
The gothic veil covers my avatar's face in mourning. I almost never cover my face either.
Also on the avatar is a silver promise ring, representing the loving 11-month anniversary.
In addition, I for once lack any kind of weapon on my avatar; wishing peace for my bff and her cat, and for not needing to guard myself from my love because I trust.
The rose I am holding is continually being switched out from red to black and vice versa, to represent love and greif.
