Happy Birthday. Wishing my amazing sister-in-law a wonderful day filled with smiles and laughter.

Wishing you great health so we can have more afternoon teas together; more wealth so you can shop for that shoes you have been eyeing for this past few weeks; more love because you deserve it; and more blessings in your life, simply because you are such a wonderful person. A wonderful birthday, sis in law!

Happy Birthday to the prettiest sister-in-law in the world. Spread your charm all over the world and bag every success the universe offers you.

People often refer to you as my sister-in-law or my brother’s wife when talking to me, but I like to refer to you by your other title: my friend. I hope your birthday is fun and fabulous as you.

You may be my brother’s wife, but you the one who helps me with my emotional strife. You may be my sister-in-law, but you the one who helps me with my emotional flaws. Happy birthday.

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.

If you drop the in-law part of your sister-in-law, you will have what I truly believe you to be: a sister. I am appreciative to such an extent that I am honored with another sister in my life, and I trust you can believe me to be your sister also.

Every candle on your cake is another year I’ve been lucky to know you! Happy birthday to you. Wishing you many happy returns of the day.

A few people aren't attached to their in-laws, and I can't resist the urge to feel dismal for those individuals. They weren't sufficiently blessed to have a stunning sister-in-law like you in their lives. Much obliged to you for enhancing my existence with your sympathetic and adoring ways.

I am so ecstatic that you have become a member of my family. May your birthday bring to you all the wonderful things that you have ever wished for in life. Happy birthday!

Sister-in-Law, I would hope that on your special day you are surrounded by love. But there really is no need to hope, because I will be there, so it’s a given. I love you, not just because you are family, but because you are a remarkable person who I am glad to call my friend.

If you drop the in-law part of your sister-in-law, then you will have what I really consider you to be: a sister. I am so grateful that I am blessed with another sister in my life, and I hope you can consider me to be your sister as well. May your special day be full of luck, laughter, and love.

I want to thank you for those moments when you looked after our kids when my husband and I went out for a date night. For always giving me tips on how to make my husband happy.
