Big sister, bigger heart.

Sister hugs are the best hugs.

My sister gets me like no one else.

Double trouble.

She's my other half.

Sister duo, unmatched energy.

Sister squad.

Love my sister more than I'll ever admit to her.

Always there for my big sister.

Raised together, bonded forever.

Happy birthday to the best sister ever.

My sister is my favourite weirdo.

My sister will always be my best friend.

Stealing clothes since forever.

Growing up with you was the best.

Sisters make the best partners in crime.
