    I can’t stop wearing these!

    Loving my 2XL high waisted bikini!!! I’ve worn them now before and during my pregnancy and they are the only undies that have felt comfortable to me as my body changes! They’re so light and breathable but still feel comforting and supportive enough. The fit is perfect… I love that the gusset is sewn down, wider, longer… even the seams feel so nice. everything stays where it’s supposed to! I never am adjusting or wiggling in them. They are sooooo soft.

    Full Coverage, Sexy, Comfy, OH MY!

    Everything I have ever needed in a more full coverage pair of undies. Not only are these GREAT with my jeans, but sleeping in these was a dream! I am a girly who hardly wears pants to sleep, I am a undies and tshirt kinda girl. THESE ARE BUTTER! They do not get stuck in places while im sleeping or doing my day to day in my jeans. The sit perfectly on my hips, NOT TOO HIGH WAISTED (which is truly hard to find with undies), and I could not see them in my pants. I am truly blow away with the structure, the softness, the way my body does not sweat, and that feeling of nothing on my body. These are an all purpose underwear that I am confident to wear with anything or without anything. TRULY A NEW STAPLE TO MY UNDERWEAR COLLECTION!
