Being overweight my whole life bathing suit season is not my favorite to say the least. I had a baby this year and I decided she would not miss out on outdoor activities because I don't like wearing bathing suits. These pants are awesome Im 51 currently around 280lbs and the 4x fit really well. It pulls up over my calves a bit but not too annoyingly. You will absolutely want something underneath, the waist doesnt fall down but isn't what Id call secure either. Swim shorts always ride up and end up rubbing a raw sport on my legs so these really help with being able to put on and worry about the baby, not myself.
