Where can I find an armani belt?

For christmas I got an armani belt, it looks great, but the actual leather belt itself isn't long enough, it looks about 7-8 inches shy. I've got a 44" waist so I was hoping someone would know where I can get a longer belt. The buckle is fine so i'm not looking to replace the whole thing, but it has a fastening system i've not seen before, it's held in place by ridges on the back of the belt. I live in the UK. Any help would be greatly appreciated.|||Go to Armarni web site|||US.
