Smart Spring Coat - Not double-breasted

[Obvs92]

I'm looking for a smart spring coat for work and home in a colour other than beige or black. Can't be double breasted or have epaulettes as I'm broad-chested. I used to have a lovely single-brested trench but can't find anything equivalent. Am I looking for a unicorn??!?

Are you looking for something like this shape and weight?

That sort of weight but I feel that style is a bit older than I'm looking for. Thanks for suggesting

Not necessarily suggesting that coat, but it's a super plain single breasted coat, so using it to pinpoint what you have in mind. What sort of things would you change? Slimmer fitting? Colour? Shorter? Lapels/more open?

What would your budget be?
