Don't know your size? No stress! We have this handy size chart to help you find the perfect size so you feel confident and comfortable in your Love Luna Briefs. Catering in sizes from size 6 to size 28 (new, extended sizing!).

We strive to align our garments sizing with all other similar products. For example, whatever size underwear you normally wear, we would recommend you buy the same size in our period underwear. If you are unsure what size you (or your child) are, we recommend you measure around your waist (smallest part, usually at the belly button) and around hips (largest part) and use those measurements (in cms) to compare to our size guide.

Please note: all FIRST styles are made in YOUTH/JUNIOR sizes

FIRST by Love Luna Size Guide (Junior Sizes)

For example, if your child’s waist is 60cm, they would roughly fit into the FIRST Australian size 8-10, UK size 10-11, USA size 8.

If the child is larger than size AUS size 14-16, we recommend going into our women’s range.
The next size up from AUS Youth 14-16 would be the Women’s AUS size 10-12.
