Happy birthday, sis! You're my favourite sibling. Don't tell the others.

Sister date day.

A sister's love never fades.

Sister selfie!

Sister hugs are the best hugs.

Sister love is the best love.

My sister's laugh is contagious.

Sisterly love, sisterly chaos.

Sisters make the best partners in crime.

Sisters: stronger together.

We grew up together and we're still growing.

My sister, my forever best friend.

Borrowed her sweater, never gave it back.

Sisters at heart, even miles apart.

My sister is my biggest cheerleader.

Stealing clothes since forever.
