Zara is a registred trademark in the name of Industria Textile (owner of Zara clothing brand) and a well-known trademark in Turkey.
It constitutes violation of the trademark owner rights' if a third party uses the trademark ZARA on the goods and products on which such trademark is registered and due to its well-known status on the other goods and products as well.
However, there are some exceptional cases in which Zara trademark can be used, e.g. use of Zara trademark by the famous singer Zara in class 43 and some exceptional uses due to the term Zara being a place in Sivas, a city in Turkey.
In any case, possibility of infringement should be evaulated case by case therefore it is not really possible to give a general opinion on use of Zara brand without knowing the scope of use.
Still, I personally do not recommend use of such term, as I know how the trademark owner's approach to IP protection is aggressive and protective.
