Thanks for the compliment! :D
Well my father has a garage and we simply used the newly bought suit for scrubbing it over all kind of surfaces - that means a lot of dirt and grime.
We also mixed the dirt into water and hung the legs of the trousers into it… for an extra coat of filth which turned out really fine.
You just musn’t shy away from getting your stuff dirty and messing around, really. Once you’re into it, it is lots of fun.
And we used a lot of fake blood (the kind they have in theatres, movies etc) and poured and sloshed (sloshed?) it over the suit, shirt etc
It wasn’t really planned out or something… we just tried to mess the suit up - all the stuff you’d never do with your clothes but secretly wanted as a kid.
Hope, that helped. <3
