Need help with clothing! my leg keeps on penetrating the skirt

hi. as you can see on the screengrab that I attached,
my leg + skirt simulation isnt working as expected…
why is my leg keep on penetrating through skirt?
tried bunch of settings in cloth configs but I wasnt able to solve this issue.
any cloth - simulation master’s opinion/advice would be really appreciated.
thanks !
