Brand New COS midnight black pants small only washed, never worn

I bought petite by mistake and washed before putting on and realizing they are petite so too short for me. These are amazing flat front, side cargo pocket wider leg pants. I’m so sad to give these up as I just bought them in Hong Kong. Material is 56 cotton 42 polyamide 2 elastane. Size is 36. They fit like a 4/6.
