when shading, you can't just go at it.. you need to choose a light source
as in
where is the light coming from exactly?
once you choose where it's coming from all you need to do is decide what the light would hit... it's easy, just think about it realistically. just takes practice and you'll be pro, as long as you always draw from the source..
personally i like to make a layer and REALLY quick choose where the light would hit the clothing then use that as a reference, THEN work on details. turn the layer visible and invisible when you shade different areas. :>
