Boris Johnson's controversial comparison of burkas to letterboxes has brought the topic of Islamic dress to the fore of public attention.
The phrase "burka ban" is often used as a blanket term for Muslim head-wear, when in fact there are several types of the garment.
So, do you know your burka from niqab, and your al-amira from your hijab?
In the West, the hijab is the most common type of head-wear worn by Muslim women.
The word hijab actually describes the general term for women covering up, but more often than not refers to scarves wrapped around the head.
Hijabs come in different styles and colours.
While the neck and head are normally covered by the hijab, the face is left clear.
The target of many veil bans across European countries has been the niqab, the veil Mr Johnson was referring to in his column for The Telegraph.
The niqab is a face veil that just leaves space clear for the eyes.
It is most often worn in Arab countries, but more and more Muslim women in the West are choosing to wear it.
When the term "burka ban" is the used in the press, sometimes it is specifically referring to the niqab.
The burka is the most restrictive form of head-wear for women, with the whole of the face, neck and head covered up.
With a traditional burka, a mesh screen around the eyes allows for sight.
This form of burka is traditionally associated with countries in South Asia, such as Afghanistan, and rarely, if ever, seen in the UK.
In Britain, the a burka can mean something entirely different.
If a woman is wearing a form of headscarf along with a cloak or garment that covers the body down to the ground, the term burka is then used.
Bans on the burka
In addition, there are other forms of head-wear beyond those already listed, including the shayla, khimar and chador.
Across Europe, a number of countries have varying degrees of bans the Islamic head-wear.
Netherlands: Face-covering clothing banned in public places (not streets)
Belgium: Public ban on clothing obscuring identity of wearer
France: Face-covering head-wear banned in public
Denmark: Full ban on niqabs and burkas
Germany: Face-covering items banned for soldiers, state workers, among others
Austria: Face-covering items banned in public
Bulgaria: Public ban on items 'partially or fully' covering face
