Alhumdulilah, I think I've found the perfect summer over garment. I purchased this over garment at Islam Orient. I'm so hype I just got it in the mail today! It comes in a variety of sizes and lengths for the petite to the tall(like Muslimah2Muslimah). It's made of light weight linen and it has pockets!! Their prices start at £19.99 which is about $33.
I got the basic brown Islamic Style Abaya with brown trim. This way I can wear it with any color(s) I want. I paired it with a mustard scarf, bracelets, clutch and nude ballet flats. Insha' Allah you like it because I love it!!!
