This outfit although cute is not very hijab friendly and should really only be worn inside the house. There are two ways I can think of hijabifying this outfit via abaya or a wrap skirt and still wear it outside.
Wrap skirts can help you hide nearly everything not too hijab friendly. :) If you are not sure what a wrap skirt is, it's basically a long rectangle with strings at the end that you wrap around your waist and use the strings to tie it in place. The following is a simple example.
Here is how I would hide the skinny jeans
This is the easy way out and I just added an abaya to hide it.
What do you think?
