zaria, i never been to any uni in doha, but i spent my life here the last 10 yrs.

i live with my parents so i dont know the safety and the environment in college, so i cant say anything about tht.

about the DOHA DRESS CODE, its hot over here during summer....u can go tank tops but at least u have to hv something to cover so its not widely open. beside u can choose any cotton materials tht suitable during tht season and its available in doha.

The problem is not coming from wht u wear here, the problem here is the peoples minds, the stare and the treatment tht u will get from ppl around you.

my big concern is tht theres alot of workers here who are far from their wifes and sure they have need tht r not fulfilled.....the only thing im afraid if u wear these kind of dress tht u just mentioned "(i do wear skirts, shorts, tank tops, sleeveless dresses etc.)" it will motivates peoples do bad things to you. but all i can say try to minimize the "openess" in way of ur dressing for ur own safety, but at the end its up to u.

since u told us tht theres alot of men coming up to u wherever u go + with the dress code u used to wear, lets say the number of men who will follow you increase to more 50% and maybe half or most of these peoples mind are bad. since u know, most of gurls and womans here are cover their body, so it will b something new if they see gurls who open.....some of them considered tht as SHOWS for them to see. and the gurls and womans here will staring at you and talking bad stuff about u.

SIMPLY...i consider tht as part of jealousy cos they cant do the same like u did. but for me, whtever ur choice, you will take the risks.

men behave differently based on their education level and how OPEN their mind can go. open minded men can understand tht but wht about the none educated and close minded one? but dont worry, theres alot of foreigners here also, they adjusted their dress code well and can blend with people here. but the last thing i heard about the rules to enter the mall in doha, i dont think they will let u enter the mall or maybe they will gv u fine for NOT DRESS PROPERLY .......but i duno if the rules change or not. you will know it by urself soon as u come here.

for everything here u have to pay except for breathing,...free air available. if u want to stay in dorms, i think they already include tht in ur expenses when u pay the money for the tuition fee and all.
things getting bit expensive here than before. but still affordable.......but i dont know the difference in the bosnia currency to qatar currency so i cant say its very expensive or cheaper here.

for ur last Q, u can say doha is heaven for cosmetic. everywehre u go u can see cosmetics shops with different brand available in doha. start from the expensive one till the cheap one. so dont b afraid ......... u WILL STAY PREETY when u stay in doha. ;)
