How do I draw baggy clothing?

[uneven otter]

I’m trying to draw the clothes of the guy who’s jumping but I haven’t the faintest clue on how to actually shade his clothes so that it looks baggy but also retains the details like the lines on his chest and stuff like that. Any advice would really help!

To be fair, since clothings of baggy one don’t contain some lines which mean folds, that will make your drawing of clothes seem not looking like baggy

So draw quite a few long lines

Just don’t do it too much or it will make into a tight one
