HOW TO CARE FOR YOUR PERIOD UNDERWEAR

Not my personal preference
I find the material to be uncomfortable and makes me feel like I am wearing a nappy (my other period undies do not give me this feeling). I do like the shape and cut of these though really feel it's only the material that let's them down and will stop me from repurchase.
Hello Period
We hope that you'll find that the fabric softens over time due to wear and washing. The bulky feeling should become less over time. Love from team Hello Period xx

Amazing Period Underwear
I love my Hello Period Undies! I’ve had another brand but I far prefer Hello. They are super absorptive, I don’t stress about leakage the way I used to with other brands, the fit it really good and they look so gosh darn cute! They’re pretty good with side leakage as well which has always been a problem for me. I find these ones easy to clean as well and love that I can throw them in my usual wash and not worry.

Love my period undies
They make me feel confident, A cause they are cute and B because I know I can trust them. I look forward to needing to put them on every month.

A cut above the rest!
These period undies are well worth the cost compared to other alternatives especially for heavy flow days. Great to feel comfortable, safe and secure in these bad gals! Other brands I've used have a low absorbancy threshhold compare to these ones!
