NWOT Sports Bra Gorgeous only tried on, never worn. Medium or Size 36 B or C

I bought it because I fell in love with the colors. And as always i washed before wearing it. Unfortunately the factory mislabeled it is labeled as an XL (38 D) and it is actually a Medium ( 36B or C) I looove it and need it on my size so I am selling it at a best reasonable offer
