Wearing Hijab as a Non Muslim

I have recently moved to Sudan and, to be respectful and so as not to stand out so much, I chose to wear hijab. I enjoy wearing it and find it comfortable. I received a good response at work and answered honestly when I was asked if this is what I would wear in my country (no) and I presume that colleagues know I am not Muslim.  All the other women in the office (who are all Sudanese) dress modestly but do not wear the headscarf whereas I wear a headscarf as well. However, I was speaking with some Sudanese and non Sudanese people (who I don't work with) and some of their comments have made me question whether I should continue to wear the headscarf. Some people in the group liked the fact that I was wearing the headscarf as a non Muslim but others said I should stop wearing it. They said that by wearing the headscarf people will assume that I am Muslim (which has been the case so far) and I might cause offence or confusion when I reveal that I am not. In addition they said that if in the future (I am here for at least a year) I choose to not wear the head scarf (e.g. when it gets hotter I might find it uncomfortable) this might cause confusion and offence and so it would be better to stop wearing it now as I have only been here a week.
The last thing I want to do is offend people and I do not know what to do for the best. I like that people at work are happy I am wearing a headscarf and I like that when I am outside I blend in. But I do not want to give people the wrong impression or make it seem that I am disrespectful, fake or a spy (one person said if I change between wearing the headscarf and not it could seem that I am a spy!)
Also, my plan was to wear the head scarf all the time at work, all the time on the streets but not necessarily when in ex-pat places. Could it be considered wrong to regularly change between wearing a head scarf and not? Is it something that I should either commit to doing all the time or not at all?
One compromise suggested was to wear a headscarf loosely as opposed to wearing it tight as I am doing at the moment.
Any advice on this matter would be greatly appreciated. Thank you.

Hi,

Welcome to the forum. I think "blending in" is a good thing as a foreigner. You will always stand out cause well, you are not Sudanese.  I lived in Pakistan and visited before I became a Muslim and whereas I was not required to wear the local "dress" it helped a. that I respect their culture b. I was not an obvious "target" from a distance per se'. 

I have not been to Sudan but I think as it is a conservative country, being as conservative as well is a good thing.

And if you like it why not? I actually found it nice to wear the dupatta (scarf in Pakistan).  Nothing wrong with it.

I bet you, you will get more positive than negative responses.

Hijab shows your modesty and gives you protection and dignity.
Stay Dignified ever. Amen.
