Just received these and will need to return. I wear a 16-18 petite size pant and an 18 in Longitude and Aquabelle brand swimsuits which fit like a glove. I have a pear shape and I'm 5'3. I ordered two sizes up as recommended by many reviewers. I am literally swimming in these. They sit way above my natural waist and the legs are so big. Shorts are a little longer than I like, but if I reorder in my normal size I hope that issue will be resolved, too.
