Little sister, big personality.

Always looking out for my little sister.

Always there for my big sister.

Sister date day.

Sisters make the best partners in crime.

Life's better with a sister.

Sisters by blood, friends by heart.

Born sisters, chose to be best friends.

My sister is my safe place.

Stuck with her for life, and happy about it.

Sisters: stronger together.

Sisters don't let sisters wear bad outfits.

Sister, confidante, co-conspirator.

Sister vibes only.

We grew up together and we're still growing.

Happy birthday to the best sister ever.
