I like the dotty coat but I'm not sure it's your style as I have observed it so far. And I do think its vibe is quite similar to the other coat's.
My style is of course different from yours, but I like to have raincoats in a couple of lengths and levels of formality.
Here are the ones I currently have...plus a lightweight bright pink rain jacket not unlike your royal blue one above. I don't have that one in Finds and I pretty much wear it only as gear.
Coat 1 is truly waterproof. It is gear-ish, very casual. For really wet days walking in woods.
Coat 2 is rain resistant, a short non-wrinkly trench that is quite flared and layers well over jackets and packs well.
Coat 3 is a classic just below the knee water resistant trench -- layers over knits and jackets and is a bit more formal.
Coat 4 is a waxed cotton utility coat -- on its way out, alas -- this coat worked a dream -- I could layer it over a thin parka and it has a ton of pockets yet somehow didn't look too casual for a lot of settings. It wasn't fully waterproof but I walked through several downpours in it without ill effect.
I would ideally like a lighter coloured coat also but haven't found my ideal one yet.
