Size Guides
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
