PRIVATE SALES: Up to -40% on our period underwear

"For a first test, we recommend wearing the underwear at home in peace starting from the third day of your period. If everything goes well and you feel comfortable, you can wear the slip all day at work or school, even on the heaviest day, as long as you don't have a hemorrhagic bleeding (copper IUD, endometriosis, hormonal disorders, etc.). And don't forget, for your 1st period slip, you can take advantage of the "Satisfaction or Money Back" offer, details below on the website 👇🏼."

"Our underwear is normally cut, so we recommend that you choose your normal size. You can also refer to the size chart found in the product descriptions. If you are between two sizes, it's better to take the larger model, as you generally don't want to wear tight underwear during menstruation." 

Most women can wear their Sisters Republic underwear for 12 hours straight, even on the day of heaviest discharge. Some women who have very heavy discharge (copper IUD, endometriosis, hormonal disorders, certain menstrual bleeding in their teenage years...) may find it difficult to wear the panties for 12 hours on the day of heaviest discharge and will likely need to change them once to avoid the feeling of moisture. Alternatively, one can start the day with additional protection like a cup or tampon and only wear the underwear by the end of the day. In any case, even women with heavy discharge can usually keep wearing the Mutandine Mestruali continuously on the other days.

"No, nothing else needs to be used, as our underwear can absorb the equivalent of one and a half tampons (in the LIGHT versions) and up to three tampons (in the SUPER versions)."

"However, if you suffer from bleeding disorders (copper IUD, endometriosis, hormonal disorders, certain menstrual bleeding in your teenage years...) and would like to wear an additional hygiene protection on the heaviest day for safety, this is of course possible."

From the selection of fabrics to the production of our Mutandine Mestruali, transparency and the desire for as ethical a production as possible play an important role for us. All our fabrics, lace, and elastic bands come from the Mediterranean region (Spain, Italy, Portugal, Turkey) and are either GOTS-certified organic fabrics or OEKO-TEX certified, making them free from harmful substances for the body and the environment. Our underwear is designed in France in our Paris offices and then produced in Morocco in our BSCI-certified workshop (the Business Social Compliance Initiative is an organization that audits companies to ensure that the working conditions of employees regarding wages, vacation, safety, etc., are satisfactory).
