Yay! It is your birthday today! Where’s the birthday bash taking place? Today, we are surely going to support wildlife by partying wildly on your birthday bash, so don’t forget your dancing shoes!
On your Big Day, dear sister-in-law, may God give you the body of Angelina Jolie, the wealth of Bill Gates, the compassion of Mother Teresa, the self-confidence of President Donald Trump, and the smile of President Obama. Happy birthday.
Dear sister-in-law, as you blow the candles on your birthday cake, take note of the fact that I love you more than Queen Elizabeth II loves to wear gloves. Happy birthday, sis.
In the world of sisters-in-law, you would certainly win a Nobel Prize because you are such an awesome individual! Have a wonderful birthday celebration.
On this day, I want to congratulate you on turning a new age and surviving another year of my brother. Keep it up! Happy birthday, sister-in-law!
May God make any extra fat on your body to either get the f*** out of your body or make its way to your bottom to make you more bootylicious than our dear Beyoncé and Kim Kardashian combined. Happy bday.
I know I’ve been a wonderful and sweet sister-in-law/brother-in-law to you ever since you joined this family, so on your Big Day, I am saying “You’re Welcome”. Enjoy your day to the max!
Sister-in-Law, you are someone that I can talk to, someone I can lean on, and someone that understands me. You are much more than just my brother’s wife, you are my friend. Happy Birthday.
I was so worried when my big brother married you because I thought that you would take my place in his heart. But now I realize how foolish I was because you have only made his heart bigger with your love. Thanks for always including me and making me feel doubly loved.
Sister-in-Law, I was trying to think of the perfect gift to give you for your birthday, but then I realized that you already have the best gift: me as your brother-in-law. I couldn’t possibly top that, so I went for chocolate cake instead!
Sister-in-Law, I know that I can always rely on you. No matter the issue, you are a constant source of help and support. Thank you for being such an understanding and generous person, and I pray that your birthday is as warm, bright, and wondrous as you are a person.
I hope your every wish comes true this year for your birthday. I know it’s possible, because when I was a kid I always wished I had a sister, and now I have you in my life. Happy birthday Sister-in-Law!
Some people aren’t fond of their in-laws, and I can’t help but feel sad for those people. They weren’t fortunate enough to have an amazing sister-in-law like you in their lives. Thank you for enriching my life with your compassionate and loving ways.
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.
My dear sister-in-law, I hope that you have a great day today, I wish you great luck and happiness, I won’t wish you love, because you have an amazing man next to you! Happy birthday!
What can I do to make you believe that Facebook did not remind me of your birthday this time! Happy Birthday to the prettiest sister-in-law in the world. BTW, Facebook does remind my brother though.
I love you more just as much as Queen Elizabeth II loved to wear a hat. I love you more than my brother loves you. So, accept my heartiest wish on your birthday dear sister-in-law and do invite me to eat the cake.
I feel jealous of you because all the focus and attention of the family has shifted from me to you. But deep down in my heart, I know that you deserve it. Happy birthday dear sister-in-law.
Happy birthday to a sister-in-law who is the darling of the family, apple of her mother’s eye, queen of her husband’s heart and the spark of her brother’s life. Last but not the least, you are my favorite too.

From Brother-In-Law

Whenever I think about you, I cannot help but be amazed at how generous and kind of a person you are. I’m truly lucky that you have become a member of the family. Happy birthday!
As the only girl in the family, I felt sad by the fact that I won’t experience how it is to have a sister whom I can share secrets with. But when you came to our life, I can’t thank God enough for giving me a sister in law who treats me like her own sister!
Happiest birthday to my wife’s amazing sister. When I met you, I immediately understand where my wife got her strength, tenacity, and charm! Thank you for being an amazing sister in law!
I’m really worried at how you will have an impact in my brother’s life. However, I was blind enough to realize how you will actually have a great impact in my own life! You have certainly made such a meaningful and deep impression to the entire family. Happy birthday!

Just wanted to wish you a Happy Birthday. Oh, and tell my brother he still stinks!
Having you for a sister-in-law kinda makes up for the fact that my brother is such a jerk. Happy Birthday!

Happy Birthday to my sister-in-law, who is way too cool to be related to me by blood.
