My mom thinks I'm fat

DestandLOVE
My mom told me I need to lose weight to fit into a dress, I wear a 4-6 for dresses, I'm 5'10" my waist is 29" and my hips are 40" and my chest is 38C. I think my weight is perfectly fine,how can I get her to see that. My doctor said I'm actually underweight, but my mom thinks I need to lose weight
