I wonder if this one of the UGH sets she used to wear.I'm sorry if I offend anyone. But that isn't the type of material you have when you are heavier round the middle. It's very unflattering.
If it is I'm sure the trousers were quite loose and I vaguely remember her rolling the top of them over. She fills them now.
The outfit will be great for hot flushes on a warm August day
