I am sure you are well able to cope and this is a rhetorical question - the sort of thing you see on William Wardrobe's blog.
It can blow hot and cold in the course of many days and you either have extra layers or tough it out. The danger is buying more gear for so-called transitional days. Not something a minimalist would do.
The other question is the whole notion of a Look. I know you are not suggesting some sort of tribal uniform but it may come across like that. I think you mean decent looking clothes with a bit of individuality and a long shelf life - not tat, or fashion dross.
Probably, but it often feels wrong during the transitional periods of spring and autumn with cool mornings and quite warm afternoons. When it all happens very early as now it is especially unsettling, don't you think?
I agree about the dangers of buying more stuff in order to try to cope though.
No, not a uniform and that is what is basically wrong with this whole thread. What is the Look?
