Ruby Love
Ruby Love's sizing and absorbency, translated onto the same scale as every other brand - so you can shop it (or leave it) with a fair comparison.
Our take on Ruby Love
A big catalog aimed at teens and swimwear, built on a garment-integrated liner rather than published millilitre capacity - it pulled its capacity claims, so we cannot verify absorbency numbers. Choose it for its range and use case, not for a capacity comparison.
Best for
Teens, first periods, and anyone after period swimwear or a big style selection.
Skip if
You want verified capacity numbers to compare against other brands.
What stands out
- Large catalog with a teen and swimwear focus
- A different, garment-integrated absorbency design
Trade-offs
- Pulled its capacity claims, so we have no verified mL to compare
- Reported to run small, so check the fit
How Ruby Love sizing runs
Ambiguous in brand materials. The sizing guide and FAQ say buy "True to size for best fit" and that underwear "should fit comfortably snug for maximum leak-proof performance." Howe
