If you're trying period underwear for the first time, it's completely normal to have questions about how it actually works day-to-day. The good news? It's much simpler than it might seem. Here's everything you need to know to get started with confidence.
Step 1: Choose the Right Absorbency for Your Flow
Not all period underwear is the same, different styles are designed for different flow levels. Wearing the wrong absorbency for your needs is the most common reason people feel unsure about switching.
-
Light flow, spotting, or backup protection: Seamless Thong
-
Light-moderate flow, everyday confidence: Lace Hipster
-
Moderate to heavy flow, overnight: Mid-Rise Brief
-
Heavy flow, maximum coverage: Boy Short
If you're unsure, it's always better to size up in absorbency, especially for your first few wears while you're getting a feel for how your body performs in them.
Step 2: Put Them On Like Regular Underwear
There's no special technique, period underwear is worn exactly like your everyday underwear. No insertion, no applicators, no extra steps. Just put them on and go about your day.
Step 3: Know How Long You Can Wear Them
Depending on your flow and the style's absorbency, most period underwear can be worn for 8-12 hours before needing to be changed. On heavier days, you may want to change more frequently, or pair them with a tampon or cup for extra peace of mind.
Step 4: Change When Needed
When it's time for a change, simply remove them like normal underwear and put on a fresh pair. If you're out and about, you can roll the worn pair up and pop it in a small bag or pouch until you're home to rinse and wash it.
Step 5: Rinse and Wash
Once you're home, give the pair a quick rinse in cold water, then wash as normal with your regular laundry, no special routine needed. (For the full breakdown, check out our washing guide.)
A Few Extra Tips
-
Have a few pairs in rotation so you're never caught without a clean one, most people find 3-5 pairs works well to start
-
Layer for heavier days, pairing period underwear with a tampon or cup on your heaviest days gives extra confidence without needing the highest absorbency style alone
-
Give yourself time to adjust, your first cycle in period underwear is often a bit of trial and error as you figure out which style and absorbency works best for your body
The Bottom Line
Using period underwear is genuinely no more complicated than wearing regular underwear, the only real decision is choosing the right absorbency for your flow. Once you find your rhythm, most people find it becomes second nature within a cycle or two.
