One of my best friends whom is studying fashion in Milan, Italy taught me how te easily spot out fake D & G wears. Either if it's jeans, t-shirts, sweaters, jackets or whatever of this brand, you must always be aware of this.
If you se that your item has on it written "Dolce & Gabbana", AND "D &G" it is 100% FAKE!
This is beacuse "Dolce & Gabbana" and "D & G" are two completely different brands! D & G is the "cheaper" version that mr Dolce and mr Gabbana have made, just in the same way that Armani eXpress is the cheaper version of the authentic Armani. so be aware, and do not be fooled! if these two are on the same piece, whatever garantee or reciet or you name it, IT IS A FAKE, 100% and many people in to fashion, probably most in to it see's this right away!
After this beeing said, have fun eBay'ing everyone and be carefull!!
