Duo Halloween Costume: Molly and Issa From "Insecure" Issa and Molly both have killer wardrobes in "Insecure", making them a stylish duo costume choice. No trip to the Halloween store is needed for this one — just comb through your own closet. What to wear for Issa: She typically rocks a casual look, so anything cute and comfy works. But Issa also knows how to show out, so feel free to take the sexy-chic route with a crop top and high-waisted shorts. What to wear for Molly: Whatever Molly wears, it's going to look like it came straight off the runway, so definitely dress to the nines in a high-fashion ensemble. Oh, and make sure you have a fabulous coat to match. Image Source: HBO
