I have also enjoyed seeing some of the other winter coats around, I am really pleased at the bright colours, there is a definite trend to bright coloured double breasted coats. This is one fashion that has made it through from the catwalk to the suburban high street quite quickly, simply because it is good. We love the bright colours, red and blue in particular, and the details of the the buttons or frogging. These are great because they look good, and are practical.
Within this style there are of course a great many variations (as there should be) with many different styles and lengths, but they are all very stylish. My particular favourites are the red, slightly military looking styles but the blues are good as well, if maybe not quite so popular.
There is also the great advantage for an over coat that they look good as casual or formal so one coat will do everything, I think the only worry would be a colour clash if the coat is shorter than the dress underneath.
I should of course acknowledge that the bright blue coat has been worn by one of nations leading style icons for many, many years; where some lead others will follow, sometimes it just takes a while for us to catch up.
