How to choose flowers for your sister
Use what you know better than most people: her favourite colours, clothing style and preference for minimalism or bold details. If her taste has changed, choose for the person she is now rather than relying on childhood memories.
A younger sister does not automatically need a “delicate” bouquet, and an older one does not require formality. Connect scale and palette to the event and her personality. A shared joke or short family phrase in the card makes the gift recognisably yours.
