No, she said her son knows she only had black sweatpants, no other colours. That is one reason I think she is being adamant about something with little solid evidence. Just because her son tells her he has only ever seen her wear black sweatpants, that doesn't mean she didn't grab a grey pair from somewhere to put on.
My daughter used to trade and borrow clothes with friends all the time. Drove me crazy. It is hard to keep track of a teen girl's wardrobe, in my opinion. And I don't think you can use that shaky claim as evidence that a parent or stepparent is guilty of disappearing her. JMO

Someone asks 'how do you know she didnt have any grey sweats, only black?
And she says :
"Because my son knows what she wears and owns more than anyone else"
[I don't see that as indisputable proof that she couldn't have been wearing grey sweats that morning...]
