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 with a teen and swimwear focus and a garment-integrated liner. Ruby Love no longer publishes a capacity figure, so we cannot place it on the millilitre scale; choose it for its range and use case rather than a capacity comparison.
Best for
Teens, first periods, and anyone after period swimwear or a big style selection.
Skip if
You want a published capacity figure to compare against other brands.
What stands out
- Large catalog with a teen and swimwear focus, thirteen sizes to 8XL
- A different, garment-integrated absorbency design
Trade-offs
- No published capacity figure today, so no millilitre number to compare
- Ruby Love says to buy true to size; the pairs are meant to fit snug
How Ruby Love sizing runs
Ruby Love’s sizing guide says to buy true to size for the best fit, and that a pair should fit comfortably snug for leak protection.
