Our Story

It started with a conversation.

Piper started with a conversation between a mother and her daughter about periods, and the frustration of not having products that felt right.

I created Piper because I was fed up with compromising my style once a month. I found myself wearing period underwear I felt I had to wear, rather than styles I actually wanted to wear.

The period underwear I've been searching for!

Really pleased with the quality of the underwear. I've been a convert to period underwear for a while but haven't really found styles like this before at this quality. Got a set of "the one" and the lace band is exactly what I was after. If you know the Primark staple thongs with a waist band like this then you will know what I mean! Perfect for a smooth and comfortable silhouette. Delivery was fast and bonus points for the packaging being paper and fitting through the letterbox so I didn't have to be in or miss a delivery. Can't wait for my period, and that's saying something!

No leaks and very flattering!

I only started using period underwear this year. Years of padding failing me and tampons now becoming painful led me to them. I'd been wearing big standard, what I can only describe as granny period pants, that I found on Amazon. I am so thrilled to discover Piper. I bought The Everyday and they are very flattering and no leaks or smells at all! I wore the same pair for 6hrs and then changed and put a new pair on for sleeping. I think 2-3 pairs a day is normal.

These are a total game changer!

I didn't know much about period underwear before trying these, and they were my first ever pair, but I'm now a total convert! They've genuinely made such a difference to how I feel during that time of the month. I feel fresh, comfortable and confident, without having to resort to the usual "granny knickers"! It's amazing to find something that's not only practical but also makes me feel good about myself. I honestly wish I'd tried them sooner and would definitely recommend them to anyone thinking about giving period underwear a go!

Piper period is literally my lifesaver

Piper period is literally my lifesaver. It has helped me through the start of my teen years with pants and styles which make me feel confident, comfortable and safe, not having to go and wear pants I don't feel comfortable in. This has been amazing and I'm so thankful, and it's built my confidence knowing I'm secure and not gonna leak. Thank you so much Katie for this brand, it has helped me so much with my period and the shipping was amazing (I recommend) x

Really impressed

Really impressed with the Piper Period Thong! Fast delivery so arrived just in time! So comfortable to wear, just like normal underwear, but with the added reassurance of period protection. I love that it's discreet, fits nicely and doesn't feel bulky at all. Perfect for feeling confident and comfortable on your period without compromising on style. Definitely recommend and looking forward to trying other styles.
