Clearly the stoilists are either stick thin and wouldn't know how to 'dress' a curvy gal, or if they are larger themselves, have no idea what constitutes a good look on a plus size body.
My friend is just over 5' and is very 'round', so she used to wear baggy sweatshirt tops that covered her tum and bum. It only made her look larger in that area ! I dressed her in a T shirt that just covered her belly button so sat on her hips and a short boxy cardigan with a calf length skirt - result ! she looked a lot slimmer and she's ditched the baggy sweatshirts. You just need to look in a mirror and see what works.
