On line they go by your body shape, pear, A frame, etc. Then you take the shape and it tells you whether you need a longer waist, shorter waist, etc. Fashion Bug uses a new way of selling closes. they did away with sizes and just do 0, 1, 2, 3, 4 or 5. and the colour defines the cut ,,, larger butt, smaller butt, etc.
Is there a Fashion Bug near you? I am sure they are on line and describe with visuals the type of pants and the cut you are looking for. Blessings and tc
