Bring out that delicious chocolate cake. Open that sparkling bottle of Pinot Blanc. Let us celebrate your bright and new chapter ahead! Happy birthday, sister-in-law!

Happy birthday to my amazing adviser and a great friend! Wishing you a huge joy and endless happiness, dear sister-in-law!

Sisters-in-law are known to have a bitter-sweet and a love-hate relationship with their in-laws. But I have a sweet-sweet and love-love relationship with you. Happy birthday.

Sisters are Forever! You are not just my sister-in-law; you have become my sister right from the day you said ‘I do’ to my brother. You are my sister forever! Happy birthday.

Now I understand why my husband is such a gentleman who is so respectful of women. That is because he has grown up with a wonderful sister like you. Happy birthday sister-in-law.

Such a wonderful person like you deserves abundance of happiness, a bouquet full of blessings, a bag full of good health and a chest-full of love. Happy birthday, my sister-in-law!

I’ve longed for a perfect timing to tell you how much your humility to my brother has inspired me to become a humble wife to my husband. Thank you for being an exemplary sister-in-law. Happy birthday.
