Here are a few maxi skirts that I've found which are currently being sold online (most of which are available in other colours) =)
For outfit inspiration featuring a maxi skirt, check out MangoWhirl, who has plenty of OOTD's as well as 3 ways to wear a black maxi skirt. Also see Aalia's (from hijabi with style) blog post for outift ideas when wearing a gypsy skirt, and the gorgeous outfit put together on the Hijablicious blog =)
Would you wear a maxi skirt? How would you style it?
