Why Choose Reusable Period Underwear?
More and more women are making the switch to reusable period underwear — and it's easy to see why. Here's what makes them so brilliant:
- Multi-layer absorbency — designed to replace pads and tampons entirely, or work alongside them on heavier days
- Leak-proof technology — a discreet waterproof layer keeps you protected without the bulk of traditional period products
- Soft, breathable fabrics — gentle on sensitive skin and comfortable enough to wear all day and all night
- Sustainable & reusable — each pair replaces hundreds of disposable products, making them better for you and better for the planet
- Cost-effective — with proper care, a good pair of menstrual underpants can last 2–3 years
- Beautiful design — because period underwear should look and feel just as lovely as your everyday lingerie
How to Wear Period Pants with Confidence
- Everyday period knickers: Wear just like your regular underwear — under jeans, dresses, skirts or loungewear. No one will ever know they're period pants.
- Period thong: Perfect for lighter days, fitted dresses and anything where a visible waistband would show. Discreet, comfortable and completely leak-proof.
- Period bikini & swimwear: Wear to the pool, beach or spa during your cycle. Our period swimwear is designed to be worn in water without leaking — total freedom, all month long.
- Menstrual shorts: The ultimate overnight option. Wear with a loose sleep shirt or pyjamas for a comfortable, protected night's sleep.
- Postpartum underwear: Soft and supportive for the weeks after birth — pair with a comfortable nursing bra or soft bralette for a fully comfortable postpartum wardrobe.

Sizing, Fit & Care Tips
- Sizing: Our period pants are available from XS to 3XL across the range. Always check the individual product size guide — we recommend sizing up if you're between sizes for the most comfortable fit.
- Absorbency levels: Light (equivalent to 1–2 tampons), Medium (2–3 tampons) and Heavy (3–4 tampons). Many women keep a mix of absorbencies for different days of their cycle.
- Care: Rinse in cold water after wear, then machine wash at 30°C in a delicates bag. Never tumble dry or use fabric softener — this preserves the absorbent layers and extends the life of your pants significantly.
- Longevity: With proper care, a good pair of period underwear can last 2–3 years — making them a genuinely cost-effective alternative to disposables.
Our UK customer service team is always happy to help with sizing or absorbency queries. We're a small, owner-run boutique and we genuinely care about getting your order right — drop us a message any time for a warm, honest response.
Frequently Asked Questions
How do period pants work?
Period pants — also known as menstrual knickers, period underwear, menstrual underpants or menstrual undies — use multiple layers of absorbent, moisture-wicking and leak-proof fabric to capture and contain menstrual flow. They look and feel just like regular underwear, with no pads, tampons or liners required.
Are period pants suitable for heavy flow?
Yes — we stock styles specifically designed for heavier days, including menstrual shorts with higher absorbency. For very heavy flow, period pants can also be worn alongside a menstrual cup or tampon for extra confidence.
Can you swim in period pants?
Yes — our period bikini and swimwear styles are specifically designed for swimming during your cycle. The leak-proof technology works in water, giving you complete freedom at the pool or beach.
Are period pants good for teens?
Absolutely — period pants are one of the most comfortable and confidence-boosting options for younger women. Soft, secure and easy to use, they're a brilliant introduction to sustainable period care.
Do you offer free delivery on period pants?
Yes — we offer free standard UK delivery on all orders over £50. All orders are dispatched promptly in discreet packaging.
How are period pants different from regular knickers?
Period pants look identical to regular underwear but contain built-in absorbent layers that replace or supplement traditional period products. They're reusable, sustainable and far more comfortable than pads — once you try them, most women never go back.
