Aritzia TNA Lilac Mega Sweatpants

Worn but in overall good condition just not as soft on the inside as they are new. Two brown marks at the bototm of the leg near the cuff - I have tried to remove with no luck at all, I think it's sharpie or some other kind of permanent marker. Open to offers due to the stain. Colour is a very pale almost white purple! Not sure the exact colour name. Size XS
