This is a problem for all girls of ALL shapes and sizes. I think this jeans/pant should be sized like men’s dress shirts, with multiple sizing details. Men have neck, chest, sleeve, waist measurements per shirt. Pants should always state the sizing for, waist, hip/butt, inseam length and maybe thigh. If fashion has long acknowledged the wide variation in men’s torso sizes (and men pay more $ for this too) than the wide variation in women’s body types should be equally marketed to.
