Love these bikinis --like the stretch and the material, but they run super small. Normally wear a 4-6 in panties and a small in these was ridiculous. Medium was OK but severe muffin top. I ended up with size large !!! With other high top Wacoal panties I wore the usual size small.
These seemed to stayed put and showed no panty line. They also fit TTS. The material was a little heavier than what I was looking for in a bikini style, so I opted for another style by this brand.
