Y3 Adidas Yohji Yamamoto Small shirt Dress Oversized with Oversized slits

when I saw this in Consignmemt I Had to have it. And that was the day I met the owner who was Excited that I had such good taste. I remember when came out, something about it got me so excited. Anyway this Piece looks like it was Worn one and Never washed. There's 2 tiny marks Pictd, of stuff you get on you during the day. Prob soap and water would work but when it comes to VINTAGE or high end Fashion, I don't think its my place to Wash it with my daughter's marker shirts and lizard water clothes. lol. plus I figure you'll wash it. Anyway about the Shirt. Or dress. It is made like it was Just on a run on skinny Asian kid and it comes down to his Knees. It is Oversized in Every sense of the word. I think pit to pit is around 30" but im looking for my tape. it also hangs down so that's not as crazy as it sounds!! The slits on the sides are More than Halfway up to the Armpit. The Stripes are in Different placement on the Front versus the back. And the sleeves are tiny. Obviously because of the fit, the cut the sleeve so it doesn't reach down to your wrist. I'm a Juniors size Medium or Large and this fits quit well. the Slit Isn't crazy. the sleeve is cute but it's Very Oversized. Did I Say Oversized yet? I don't know If this was one of those kinda Runway pieces or made to be a Man's tshirt or a Dress as I Cannot find an Exact Match Anywhere. Let me know if you Can and I'm happy to negotiate!! as I female I would Wear it with a tin black belt. Thanks
