Ordering Period Underwear Online in Hong Kong: Sizing, Exchanges and Delivery

Buying underwear online without trying it on first is a reasonable thing to hesitate over — it's the single biggest reason first-time buyers stall out on the cart page rather than the checkout button. The friction isn't really about the product; it's about not knowing what happens if it doesn't fit. Here's the practical version of that answer.

Getting the size right the first time

Kiri's sizing runs across waist and hip measurements rather than dress sizes, since fit around the absorbent gusset matters more than overall garment size. Our size guide walks through exact measurements for each size band, and the general rule is: measure rather than guess, and size down if you're between two sizes — the gusset has to sit flush against you to work, and a waistband with slack lets it shift out of place. If you have sensitive skin, our guide on what to know before you switch covers fabric and fit considerations too.

If it doesn't fit

Exchanges are straightforward — our Delivery, Returns & Exchange page covers the exact process, but the short version is: contact us with your order number and the size you need instead, and we'll sort the swap. Not sure if your size is actually wrong or just unfamiliar? Here's how to tell. This is worth knowing before you order, not after — the exchange process exists specifically because getting sizing exactly right on a first order isn't guaranteed, and it shouldn't need to be for you to try the product.

Delivery within Hong Kong

Orders placed within Hong Kong are processed and shipped locally, with delivery typically completed within a few business days of dispatch. You'll receive tracking information once your order ships, so you're not left guessing — full details are on our Delivery, Returns & Exchange page.

What to expect on your first order

Most first-time orders are one or two pairs rather than a full rotation — a reasonable way to test fit and comfort before committing to more. If daywear and nightwear both interest you, our bundle sets are usually the more economical way to try both at once rather than ordering separately later. Worn and cared for properly, a single pair lasts around two years — so testing fit with one or two pairs first is a low-risk way to start. You can see the whole period underwear range before deciding.

Questions before you order

If anything about sizing, absorbency, or delivery timing isn't covered here or in the size guide, our FAQ has the fastest answers before you place an order, not just after.
