Don't be afraid to use references, especially when drawing clothing and especially when starting out drawing. Remember the clothing doesn't perfectly stick to the body and puffs out a little bit. Focus the fold lines around where things bend, like the joints, and don't draw as many lines on the rest of the cloth.
Take into consideration the material you want to portray as well. A lighter fabric like silk will have many more lines than something heavy like wool. I'm not the best at explaining myself, so I'll attach an image.
Finally, line weight is very important. It makes the piece interesting. Make the lines thicker in parts where the cloth would fold to emphasize the shadow, and use a slightly thicker pen for the overall outline of the shape.
Second image is the shading point I tried getting across but it got the point across far better. It's by a really incredible artist I follow on twitter by the name of Celestial Fang, but they deleted the attached tutorial because twitter pulled a twitter on them. Neutral light has its time and place though, certainly.
I hope this helps, good luck!
