Pantless seasons

Well, don’t know the truth about that, but they got me interested!

I like this look for autumn and winter a lot: the gentlemen’s jacket combined to no pants – so simple and easy, which I’m all for and therefore is obviously the right way to go. 

Now how can you transform this easyness to suit these latitudes? (It’s 10°c at the moment.) Mmh, I wouldn’t mind doing a trip to good old Paris with research in mind.
