100% authentic! This was from the first original collaboration between Adidas x Danielle Cathari. Creative design and placement of the famous 3 stripes stands out from the classic brand. Sold out in under 10 minutes globally. Excellent condition, only worn a handful of times. This jacket is a XXS but boxy fit, very forgiving it definitely fits an XS also. I have the matching skirt in XXS available as well. Bundle for a discount! Pit to pit - 21” Shoulder to hem - 18”
