In Australia, UGG specifically refers to sheepskin boots, also known as "ugly" boots. However, they have now become an irresistible fashion item. In Europe and America, UGG usually refers to the American brand UGG AUSTRALIA. Of course, many people in the West also know that UGG generally means sheepskin boots. As for us over here on this side of the Earth, we each have our own opinions. Some say that only UGGs from the US are the real deal. Others claim that only UGGs from Australia are the authentic ones. Still others believe that any genuine sheepskin boots can be called UGGs. Then there are those who don't care about the details and call any boots resembling UGGs by that name, regardless of material or brand — even if the boots aren't made of sheepskin but just look similar. In the end, it's a case of different strokes for different folks.
