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.
Size & material: sizes XS–L (waist 58–77 cm). Body 70% nylon, 30% spandex; absorbent pad top layer 84% modal, 8% seaweed fibre, 8% spandex.
How to wear
Designed to be worn on its own. Choose daywear, which holds 50 ml, for light to moderate days, and nightwear, which holds 75 ml, for heavy days and overnight. 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 leakproof 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.
More questions
How many pairs do I need?
Most people are covered with 3–5 pairs: day pairs, a nightwear pair, and a wash mid-cycle. Bundles are the cheapest way to build the set.
How do I change them when I'm out?
Bring a spare pair and a small wet bag — that's the whole system. Rinse the used pair when you get home. Most days you won't need to: nightwear's 75 ml covers a long day out, and plenty of people plan a heavy day around one change at home rather than one in a public bathroom.
How fast do they dry?
The fabric is quick-drying — line-dried overnight, they're ready by morning, which is what makes a 3–5 pair rotation work.
Reviews for this product
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 |
