Looking for a Navy coat

[daquee101]

So I have an M&S coat in a cream colour (black version is on the pic attached). It's pretty smart but I'm cautious to wear it around DS for obvious (and sticky!) reasons.
Therefore I'm looking for a navy version, from anywhere , which looks smart and is warm too. Budget £200 but hoping for much cheaper , im a size 8 and medium height , thanks!

A girl I work with had a gorgeous navy coat from New Look. Did NOT look like it was from there, it was lovely. Similar style to that one you've got already but a bit more "relaxed" for want of a better word.
