Stylish Sweater

I found this pattern in VogueKnitting Magazine. Isn't this lovely? Actually I don’t really like sweaters with cables. All the sweaters with cable that I saw so far are very thick, boxy and not stylish at all. But this one is definitely a winner. Someday I will make something like this.

After looking at the photo again, I think the sweater itself is quite basic. It is the belt that makes it look stylish. Probably I need to buy a similar belt. Anybody get any ideas where to buy this type of belt?
