And welcome to the Polish forums.
i'm going to Poland this December
It is cold, in comparison to the Philippines it is very very very cold.
Hat, scarf, gloves, warm boots, thick pair of tights, a big jacket etc...
i have very little idea about fashion and clothes in cold places like Poland.
Something on the lines of skiing clothes, I think would not look out of place and keep you warm, without the goggles of course.
But wear jeans with thick tights underneath.
I have worked with many very good Philippinas and they find it cold here in Europe in summer.
Have a great time and remember there is no such thing as bad weather, just the wrong clothes :)
