This skirt is from LuLaRoe (Sophia skirt), but I found some similar ones. The JCrew Factory skirt is antique navy. It’s a bit darker than spring navy, but it’s a great option, especially for the bottom half of your outfit. The one from Banana Republic Factory is elastic waist (like mine), so even though it only goes to XL, I’d gamble on it as a size 18 who carries her weight in her belly
