    AMAZING

    I have waited so long for a pair of swim bottoms to fit like this and to actually be a flattering thong without making me feel like I’ve been tied up with butchers string and things popping out where they shouldn’t. I’m in between sizes right now and I’m losing weight pretty quickly, but it feels great to know that I can sit the waist up higher or lower depending on how I’m feeling and knowing it won’t slip

    Truly fits like comfy undies

    I have struggled for years to find a bathing suit bottom that fits my booty and larger thighs, and goes high enough so that I feel somewhat covered up. These bottoms fit like my comfiest underwear and don’t dig in like most other bathing suit brands do. I highly recommend the high waist thong for any curvy gurlies who are sick of unflattering bathing suit options digging into your butt and thighs. These are super sexy and super comfortable. 🔥🔥🔥
