Gucci Marmot Belt Black Thin

Brand new, never worn Gucci Belt in the thin size. I never got to wear this belt as I had a baby shortly after and I grew a few sizes. Sadly the belt does not fit me around the hips any longer as it did when I originally bought it. It could still fit around the waist with a dress but I am very conscious of the way I look post baby. I have never worn this belt outside the house so it is practically brand new. It's a size 80.
