I strongly advise looking for fold/clothes tutorials, unfortunately on pinterest, or on deviantart (tumblr/google/everywhere else). There are tons and tons of useful tutorials that explain everything perfectly. Check @grizandnorm’s tutorials [x][x] very simple and easy to follow. Check this tut [x] by Louie del Carmen, here’s a nice tut [x] by juliaim15
on deviantart. Look for some more (even in my faq is one…) and use references, draw from life, try to understand why all those folds do what they do 🙂
rant under the cut (it has nothing to do with the ask btw xD)
