Can I use Sisters Republic underwear coming up to my period or before my first period?
Yes of course, Sisters Republic period underwear is pretty, comfortable to wear and very thin (between 1.5 and 3 mm), so nothing like the thickness of a sanitary towel. That means you can wear whenever you like, without discomfort and without worrying that they are noticeable to you or anyone else. They are a great option for the days leading up to the start of your period to help prepare you for any surprises.
