I looked everywhere for something modest. These met the need. I am 50, 5'2 and 135 lbs. Small waist, big bum & thighs. Poochy belly. So.Hard.To.Fit. I typically wear a PM or 10P. I ordered a medium and a large. I kept the large. While dry they are perfect! The mediums were a little snug for my preference. After being in the water the large were a little...large. So in hindsight I may have kept the medium. But while out of the water the large were perfect. I was very happy with my purchase. The quality is high. This was my first purchase from Roxy as I believed it to be for teen-20something, thin and tall. I will be a return customer.
