I saw this downloadable pattern online at sewingpatterns.com , the style in blue looks like it could be customized as a sporty jilbab. Its $5.99 US for download here . The other styles look cozy and can be worn around the home.
Some Muslim women (and some men too) have the tendency to criticize sisters for how they wear hijab, for them not fully covering, even for not covering their feet. Many women are simply not ready for hijab, they have accepted Islam but they are not ready to take the next step. They may take baby steps, wearing a small scarf every now and then, wearing a long blouse over jeans, but are not ready to take the plunge into being a full time muhajabah. This may take time, as everyone is different, it may even take some sisters YEARS to wear hijab full-time.
