They looked sooo cute in these that I just had to try one out myself. After a fun afternoon in Harajuku, I had one offered to me at a discount in a used store and I decided to try it out!
Personally I like it! Nice points are that it's very warm, easy to coordinate with, and not real fur (mine isn't, at least)! However, some negative points are that you can't wear it with anything that has a hood and it looks strange with shirts or sweaters that have a low collar.
Here is how I ended up coordinating it. Admittedly, it was a very comfy, lazy outfit. I think it might needs some little je ne sais quoi before it's street-ready. Maybe the tights and undershirt need to be a lighter color? Hmmm... Thoughts?
