100% Authentic as you can see in the detailed pictures.
The hoodie is oversized and fits like an XL.
It is the heavy version of the hoodie, so it is one of the most sought after Vetements pieces. I'd say it is not just a hoodie, but an art.
The hoodie is in excellent condition.
The item will be shipped from Tokyo, Japan via express courier. It should take about 7 days to reach the destination.
If you have any question, ask away.
