l do not sketch because l find it messy looking.
i get sorta stressed when l draw fashion designs thinking that it is not good enough, if it is the right way to design, & other crap.
some retired fashion designer said the way i'm designing is not proper, she says i'm actually drawing clothing too realistic & does not look like fashion designs at all. but she is very old fashioned.

my mom & other people who've seen my work said i'm really talented but whenever l see those fashion sketches in the magazines, they look drawn with paint & a brush. so in what way do l sketch, draw, or paint?
i design clothing with a black pen, pencil, crayola color pencils, crayola crayons, & crayola markers.

hi well to tell u the truth .. first of all u need to bring the right dimensions or scale of the models that they design on .. like, u know long legs low waist. then u trace a model on a tracing paper then start to draw u clothes on it just like that ! :) second : coloring see some coloring techniques on this web site & learn how to color.. to get that professional look in designing ;)
