Authentic, have had it for a few years but I’ve lost a lot of weight and it’s too big now. I’ve worn it only about 3 times total. I’ve taken great care of it and the brass double G is in excellent shape/like new condition. Size 95/38 This size is sold out on the Gucci website and rare to find in store. I will mention: I’ve punctured two additional holes inward with a belt hole puncher. I’ve circled them in the last photo for reference. They look very clean and you can’t really tell they’ve been added. Thanks for your interest.
