Sis, you're my favourite.

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

Sisterhood is the best hood.

My sister, my sunshine.

We shared a room. Now we share everything else.

Sister bond: unbreakable.

Sisters in style.

She knows all my secrets and still loves me.

Sisters: the family you get to keep forever.

Little sister energy.

Sisterly love, sisterly chaos.

We fight like cats but love like sisters.

My sister is my favourite shopping partner.

Sisters make life sweeter.

My sister's laugh is contagious.

Little sister, big personality.
