Stand with your feet together and measure around the fullest part of your hips and buttocks. Keep the tape level and snug, but not tight. The number where it meets is your hip measurement.

The 3-layer liner absorbs and locks in leaks, whether you're in or out of the water. When washed with detergent, blood releases through the top layer for a fresh, clean suit.

I just bought a second pair of these awesome swim shorts. I deeply love them for three reasons:
1) Excellent quality holds up to swimming 3-4 times a week. Still have their shape and elasticity.
2) They work as advertised. I bought them for a dance performance and they functioned perfectly.
3) They fit fantastic. Just like the image, they hit right under the navel. Keep my belly roll contained nicely and don't ride up.
