Purple prom dresses are one of the major trends of 2019, and they come in plus size options that will work well for fat women. You must see if there is a way for you to get a color that you love, and the purple that you find will accentuate your body, your eyes, your skin tone, or your hair. You could choose a lighter purple because it feels feminine, or you could choose a darker purple that will make you look much more mysterious and seductive. These dresses fit big girls in all the right places, and you can show off all that you love about your body.
