Why Sooyoung always with her furry sleeves?

I think its supposed to make her body look more full or show more volume for her top side. Normally if you have a nice lower have of if your wearing shorts, I guess its a good I idea to balance it with a full top....in other words I don't know

Honestly, i don't know. she had way prettier outfits and hairstyles before, it looks like she's the new Hyoyeon now -__- they always try to make her look older
