I love these scarves. I love the way they look wrapped around the neck. I am well aware of the political association as well and since I support the Palestinian cause (AND a peaceful resolution in the region which insha Allah can be achieved one day sooner rather than later), I wear it with no qualms. Should anyone ask... I know the meaning of my fashion statement.
A djellaba is an outer garment that both men and women wear over their "regular" clothes when out in public. As far as I know the word "djellaba" is Moroccan, but the concept is Middle Eastern (ex: the abaya for women). This pic (from
http://www.desertstore.com) is a good example of a common djellaba you would see in Morocco and is a woman's version (note the tassel on the hood that the man's version would never have). I have one that is similar, but with beautiful white details embroidered in the fabric. I wear it when visiting Morocco (my husband is Maghrebi), but I never wear it in the US. However it would not surprise me to see them on the streets here in the States one day. There are some BEAUTIFUL djellabas out there and they can look really pretty on if done right.
You could most likely buy the kahfiyah (scarves) in almost any Islamic store in the UK that sells scarves and accessories (at least that's the case here in the States). But, you can buy them online too. Here are some links:

There are more, but you just have to look around a bit.
