I’d order another pair but I can’t decide which colour. So awesome.

Another great product from Hernest

Love these undies, they are soft and comfortable. I wear them for sleeping but occasionally for every day wear. I am typically a small or medium in underwear and the small fits perfect. Thanks again for all you do Hernest!

Summer sleeping

I’m saving these for the summer but I love the fit and feel of these! Nice coverage and don’t ride up, I went for a medium and they are perfect, my hips are 39”.

I loved the idea of having a pretty and dedicated pair of brief and tank for lounging and sleeping. I paired it with the Veronica tank, both in the rich and beautiful Copper colour and made of a soft and light fabric. The Betty Briefs are covering me enough that I can freely move around the house without a robe. I love the high waist. I wish however the areas where the elastics are were more padded for optimal comfort. Size large fits me well; my measurements are as follow : waist: 35”, hips: 42”, inseam: 24” (waist to waist).
