An olive green trench that’s not stiff and doesn’t crease?

[ExtraFox18]

I have only ever seen trench coats with stiff material or thin material which creases. Where can I get a really nice trench still coat which is neither stiff nor creases abc is simple in design ? I saw Meghan M wearing such a coat in some pictures. Any suggestions ?

Maybe something like this OP ?
It isn’t olive though - I Could have sworn they did that colour too ..
