Spoiler: inclusive sizing is here (and growing!).

šŸ“ What size should I get?

Here’s a handy table with our updated sizing. This is based on AU sizes and waist measurements, to make it easy.Ā 

šŸ’¬ Fit Tips

  • Between sizes? Size up for comfort (especially on bloated days)
  • Like things snug and secure? Stick with your standard AU size.
  • Want heavy protection? Go for the Heavy absorbency styles... extra layer, same comfy fit.

šŸŽ‰ Extended Sizes Are Almost Here!

We’re so excited to be expanding our size range:

  • 2XL & 3XL are arriving September 2025
  • 4XL is dropping October 2025

Because everybody and ā€œevery bodyā€ deserves to feel confident, comfy, and leak-free.


🩲 What's the difference between Regular and Heavy?

  • Regular: 2 absorbent layers, gusset-only coverage - perfect for everyday flow or as backup with a cup.

  • Heavy: 3 absorbent layers, back-to-front coverage - ideal for overnight, postpartum, or heavier days.

šŸ‘‰ Pro tip:Ā 

Pair with a Luxe Wet Bag to carry spares or backups discreetly on the go.
