what is a bad hijab for muslimahs?

For me a bad hijab is no hijab at all.. and worse than that is the muslim girl walking around pretty much naked, not covering anything of her body. now im not talking about her faith or her love for Allah SWT, so i dont need everyone commenting on . I am just talking about dress here. some people wear niqab, others wear hijab, others wear a half-hijab style , while some wear no hijab but still wear modest clothing... then there are the other types of muslimahs... who wear skanky tight clothing, short short skirts, .. you name it. now im not one to force hijab on anyone, i myself believe hijab is a process and we all go through different stages and level of our hijabiness, but there is no excuse for a MUSLIM WOMAN . if you dont want to wear hijab then thats your choice.

these two following girls are muslim. i think it is disgusting to be walking around on a stage, like this, representing Islam and their respective Islamic countries at the same time. remember i am not talking about their 'no hijab' choice, im talking about the fact that they are completely nude while telling the world they are muslim. No one asks to be a role model, but with girls like this walking around, giving out the wrong idea to younger muslim women and girls.
