I buy the Mate Flat Front full rear suits with drawstrings so I can wear them low and tight in front, and they stay on in the ocean surf. I wear these at crowded beaches as they look nice, front and back. Latest album, Kae Jong, Rang Ji, and Nu Yo size 2XL and my hips are 39" I added the Cho Hyun I pouch suit for comparison
