The red flag that is being shown is that he is controlling what she's wearing and making an innocent outfit out to be more than it is. She could respond by saying that he doesn't get a say in what she wears, not to do it again and that if he does do it again she'll end the relationship.
You can't wear that dress to dinner with our friends, it shows too much of your arms and legs!
The red flag being shown here is he is controlling what she eats and he's underhandedly making her feel bad. She can respond by saying she'd like to eat whatever she wants and she doesn't need his permission to do so, she could also tell him how it makes her feel when he makes comments like that and to not do it again.
She'll have a salad, she doesn't need the burger and fries.
