Period Underwear
Celeste Blue Daywear Panties
$288.00
Details
Kiri's classic bikini-style, seamless period panty — our signature daily staple for the time of the month. Thin enough to forget, absorbent enough to trust. The Celeste Blue was drawn from the founders' love of a clear blue sky: light enough to wear even on your period. Moderate–heavy absorbency, sizes XS–L. Wear it, wash it, love it — then do it all over again. Designed in Hong Kong with love.
How to wear
Lighter days — wear them on their own; the extra layers replace pads while keeping you fresh and dry. Heavier days — wear as leak-proof backup alongside a tampon or cup. First time? Test the waters towards the end of your period when your flow is lighter.
Absorbency & fit
Moderate–heavy absorbency: 50 ml — about 5.5 regular tampons / 10 teaspoons. Low-waist rise with a full-coverage back. Fitting can vary between styles; if you're between sizes, we recommend going down a size.
Care
Rinse under cold running water before a cold machine wash. Line dry. Do not bleach, soak, add softener, tumble dry or iron. Cared for well, one pair lasts years.
The science
Four layers of leak-proof technology trap and lock liquid inside water-resistant, moisture-wicking materials: an outer shell, a stain- and leak-blocking layer, an absorbent core holding up to 5.5 tampons' worth of flow, and a barrier that keeps you comfortable. No dioxin, chlorine or rayon.
FAQ
Will it feel wet? No — the top layer wicks moisture away instantly. Can I wear it all day? On moderate days, yes. Does it smell? The antibacterial layer neutralises odour all day.
Size Guide
Two measurements are all you need — waist and hip. If you're between sizes, the rule depends on the piece: size down for panties, size up for bras.
Panty sizes
Between sizes? Size down. The gusset has to sit flush against you to work, and a waistband with slack lets it shift.
| Size | Waist | Hip |
|---|---|---|
| XS | 58–62 cm | 80–84 cm |
| S | 63–67 cm | 85–89 cm |
| M | 68–72 cm | 90–94 cm |
| L | 73–77 cm | 95–99 cm |
| XL | 78–82 cm | 100–104 cm |
Bra sizes
Between sizes? Size up. The four-way stretch takes up any slack, while a band that is too tight will dig in.
| Size | Asian sizes | US/UK sizes |
|---|---|---|
| XS | 65C · 70B · 75A | 30C · 32B · 34A |
| S | 70C · 75B · 80A | 32C · 34B · 36A |
| M | 75C · 80B · 85A | 34C · 36B · 38A |
| L | 80C · 85B · 90A | 36C · 38B · 40A |
