Maxi dress, apparently its easy to sew: Its just 4 rectangles. Measure shoulder to hem length, then girth at widest part (hips?) and divide by Add seam allowance. Sew allowing for neckline, arm holes. No pattern needed.
I am literally SO obsessed with this dress. Roman Holiday Dress: Features an elegant wrap-style bodice framed by long airy chiffon sleeves, double deep V-neckline, glittering gold sequin banding at waist, and a graceful gathered skirt to finish.
