Blue summer coat

[Wallywobbles]

Bit of a panic. Going to a memorial service on Wednesday and need a smartish summer coat. Preferably navy. I have a 2 hour window in central London tomorrow to find it. Any thoughts.

Im 5'3 and size 14/16. So basically a short arse with boobs.

M&S do a navy trench that might fit the bill?

Comes in a few different colours, including navy

With a 2 hour window I'd head to either Debenhams or John Lewis. Several smart macs and trench coats in navy on the Debenhams site as well as a few non-mac styles.
