Search fashionary, there are books for sketching human bodies. Similar ones are also possible, but with different styles and different quality. The premise is that you should draw a style map as you said. The sketches of those great designers look very simple, just like the design process of "an epiphany" that Kan Kan talked about in their interview, with three minutes on stage and ten years off stage. In fact, you may give up because you don't have the patience to constantly revise the prototype sketch before you fully grasp the proportion of the human body.
As an art student for ten years and a clothing major for more than five years, I actually began to notice fashionary after graduating from college, and I looked lazy. It's no use buying it myself, but I recommend it here. One is concise and professional, and the other is that it can save time and effort to enter the state as soon as possible. Without a solid foundation in this field, you are a semi-layman. Like many people who are interested, the drawings for the purpose of fashion design are not fashion illustration's illustrations. The sooner you build your own template, the better. Don't be too envious of all kinds of sketches on the Internet. My collection peaked in my freshman and sophomore years, and I can't remember how many. Later, when I changed my computer, I only backed up a small part in DropBox, because I knew that I didn't use it much after four years of graduation, and I wouldn't take the time to do it after further study. When you want to make a style, all kinds of subtle changes have to draw different manuscripts, so you are not allowed to draw each manuscript by hand in time. Another practice is deeply felt by students studying in maloney: Can I use the improved model version when drawing style drawings? See comments. It should be noted that some places will be regarded as plagiarism if they are made entirely with fashionary, so the most professional way is to make your own model, but still pay attention to efficiency rather than drawing it yourself. Time is precious, don't spend it on drawing many patterns. If you really want to design it, you need to constantly improve it.
I recommend a skirt for you, 778, 600 in the middle and 396 in the end. You can find it by combining them in order. You can get some tutoring materials. There are on-site teachers in it every day. The teaching method is relaxed and humorous, and professional counseling is provided. Strong learning atmosphere. You are no longer afraid that you have no motivation to study alone. You are welcome to join us. Don't come if you just join.
Then practice. Primary school began to draw people, and junior high school copied the wide-shouldered model in the old costume design book. The teacher repaired the waist of the female model for me, and I still feel ashamed. High school is an art student, and many draft papers have my unprofessional design sketches.
I just drew it in college.
