Dolce and Gabbana men’s extra large wool sweater / Fake?

Dolce and Gabbana? men’s extra large wool sweater with front zipper and red rivets. i’m not sure if the sweater is real or not. It has dolce tags and the label looks like the vintage dolce of its time but I’m not sure so I’m selling it as a regular sweater. Measurements are armpit to armpit 50 inches, from the nape of the neck to the hem is 31 inches
