Great option for pregnancy

These are the first briefs I’ve purchased for pregnancy. I wanted organic cotton based ones where possible and therefore chose these ones from Subset. They fit great and are super comfy. I’m so pleased with them I plan on purchasing more types.

Perfect preggo undies

I’m in my second trimester and already feel huge. These undies are perfect for my rapidly growing tummy. They’re so comfortable and don’t dig out at all! Would totally wear these post pregnancy.

so comfy!

Love the full coverage and fit of these. I prefer this style to the over the belly one. Im 5'2 and pre pregnancy size I wore Subset small. I bought these in a medium and they're perfect.

Best Maternity Undies!

I’ve really been loving these underwear! So comfortable! Always the ones that I’m digging through the laundry to find! Initially, I had an issue with the ham on a pair that I received, but the staff at subset was so great! And helped resolve the issue quickly! Definitely recommend to all my family and friends!
