How to draw Sweaters Chibis or Manga

Now that I've (finally :`) hauled out my sweaters and hoodies from storage up in the attic, I wanted to point out THREE things that make a drawn sweater a sweater, instead of some skin-tight long-sleeved shirt. 

 #1. sweaters often have thick collars. Show the width by giving it a rim as shown. Without this, the sweater seems too thin and un-three-dimensional.
#2. Every seam in the sweater will create a little indent, puffing up on either side. This will help convey the thickness of the material.
#3. Because sweaters, hoodies, jackets, etc. are weighty, the material is always drooping downwards, in triangular sections shown in the simplified doodle.

There are much fewer wrinkles in heavy cloth, than, say, T shirts and a lot of sweaters come in patterns. Google up a couple references to find a pattern you like and use it to create a more realistic picture.
I also wanted to note that it's a given in the fashion industry for girls' seams to point inward, while men's' point outward. The logic behind this is that it creates a 'broader shoulders' effect for the guys. It's the same with your manga( or chibi) characters! If you want a character to be more girly, slant in; more manly, slant out. It makes more difference than you'd think!

 It's not just for chibis! Handsome young men can wear them too. *insert smirky emoji*
#1 thickness in the collar( and sleeve cuffs).
#2 Indent in seams( and it's goin' outward).
#3 The thick material of a sweater droops downward( nothing to put in parentheses here).

Have an awesome sweater-filled, hoodie-wrapped, fuzzy-sock autumn!
