I would have to say that the 2009 november monthly collectable is my favorite. I grew up on my little pony and the collectable feeds the little girl in me. I always wanted to be a fairy princess with a pet unicorn...gaia made that happen. ^.^
If I had to choose another favorite it would be two collectables in fact, the current omg scarf, and the original OMG from 2003. They are like squishy little demon babies that don't know they are bad yet. Then you made them into clothing and thats even better. I have to say the OMG is one of the better ideas in items that gaia has had.
My fav is got to be wild things i love the idea of a mount i play alot of games and never had had enough money to get a mount so this makes me feel important that i have one here plus the tiger and wolf are just too cute
My favorite November MC is the autumn glory because my favorite season is fall. Especially those couple of weeks where most of the leaves have turned brilliant colors but haven't been whisked away by the wind yet. The autumn glory captures this well, along with the growing chill. I've always loved the little acorn mug with the steam curling up from it.
