How to Choose a Period Panty: A Complete Buying Guide (2026)
What's in this guide
Period panties have become one of the most popular period products in India — but with so many options, how do you choose the right one? This guide breaks down exactly what to look for.
What is a period panty?
A period panty is menstrual underwear with a built-in absorbent core. You pull it on like normal underwear — there's no pad to position, no belts, nothing to shift. It gives 360° coverage, which is why period panties are so popular for heavy days, overnight and travel. They come in two types: disposable (single-use) and reusable (washed and worn again).
Disposable vs reusable: which suits you?
| Disposable | Reusable | |
|---|---|---|
| After use | Tear, wrap, bin | Rinse, wash, dry |
| Best for | Heavy days, travel, postpartum, hostels | Regular home use, long-term savings |
| Upfront cost | Low per pack | High per piece |
| Monsoon drying | Not an issue | Can be difficult |
| Convenience | Highest — nothing to carry back | Needs washing and a wet bag when out |
Neither is universally better. Many women keep disposables for heavy days, travel and postpartum, and use other products the rest of the time. If you want maximum convenience and no washing — especially for heavy flow, travel or after delivery — disposable period panties are the practical choice.
The 6-point buying checklist
Whatever brand you consider, judge it on these six things:
- Correct size range — does it actually fit your waist measurement?
- Wear time — how many hours of protection does it promise?
- Coverage — does it offer true 360° protection?
- Fabric — is the top layer soft, breathable and cotton-feel, or plasticky?
- Pack size — how many panties per pack, and what's the real per-unit cost?
- Honest claims — does the brand make believable claims, or inflated ones?
Why this matters: a cheaper pack of 5 rated for 8 hours isn't necessarily better value than a pack of 10 rated for up to 12 hours. Compare wear time and pack size together, not just the sticker price.
Getting the size right
This is the single most important choice — most leaks are fit failures, not absorbency failures. Period panties are sized by waist measurement in centimetres, not dress size:
| Size | Waist |
|---|---|
| M–L | 60–100 cm |
| L–XL | 80–120 cm |
| XL–XXL | 100–140 cm |
If you're between two sizes, size up. A snug-but-not-tight fit seals at the legs; a tight one pulls the leg guards away and leaks. Our full size guide shows how to measure properly.
Absorbency and wear time
Look for a clearly stated wear time. SheWon period panties, for example, are built for up to 12 hours of protection — enough for a full night's sleep, a long journey or a full working day. Remember that wear time is a maximum, not a target: change sooner on your heaviest days. Match the product to your flow, and use your first pack to learn what your body needs.
Fabric and comfort
The top layer — the part against your skin — decides how comfortable a period panty feels over a long wear. Look for a feather-thin, cotton-soft, breathable construction. A soft, non-woven top layer reduces friction and lets skin breathe, which matters especially if you're prone to rashes or chafing, and in India's heat.
Pack size and value
Compare the real per-unit cost, not the headline price. Indian packs range from about ₹35–₹70 per panty. A pack of 10 usually offers better value than a pack of 5. Factor in wear time too — a longer-wearing panty may mean you use fewer per day. And weigh in the cost a leak avoids: a stained mattress or ruined outfit isn't free either.
Once you've matched size, wear time, coverage, fabric and value, you'll have a period panty that genuinely fits your days — which is exactly what SheWon is built to be.

Judge it on six things: correct size range for your waist, stated wear time, true 360 degree coverage, a soft breathable cotton-feel fabric, pack size and real per-unit cost, and whether the brand's claims are believable. Getting the size right matters most, since most leaks are fit failures.
Neither is universally better. Disposables suit heavy days, travel, hostels and postpartum because there's no washing and nothing to carry back. Reusables suit regular home use and long-term savings. Many women use disposables for heavy and travel days and other products otherwise.

Look for a feather-thin, cotton-soft, breathable top layer rather than a plasticky one. A soft, non-woven surface reduces friction and lets skin breathe, which matters if you're prone to rashes or chafing and in hot, humid weather.
