Thanks Laurie

I only checked the last box in the sim settings, ill do it again with all three checked and your suggestion on the resistance/density, I did try to mess around yesterday on another dress but it sorta stetched and looked like stringy goo lol so thought it better i didnt try messing with the dynamic controls

I might try abit of a noise bump on the material to see if those squares disappear, (lol i can see this turning out as a furry dress)

I'll let you know how i get on  :)
