I believe that you will have a great day sister with that amazing man by your side today.

Happy Birthday to my gorgeous Sister-in-law, wish you become younger every year instead of getting older. Eventually, it will increase your spending on anti-ageing products.

They can’t go uncelebrated especially when it is the special day of your sister-in-law.

Why not drop a special greeting and make her smile on her birthday?

Sister in laws are like muffins in a bad day. They make you all warm and fluffy inside, chasing the bad vibes away.

Not only was I blessed with a great husband, but also with an awesome sister-in-law. Life gave me a wonderful package deal! Best birthday!

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. Wonderful bday, my sister-in-law!

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

Wishing you a joyous day my beloved sister-in-law, as this is your special day.

You are like a wild flower in a desert – rare and delicate.

You are like a diamond in a rough – unique and pure.

I am blessed to have met such a nice and beautiful soul. Best birthday, my dear sister-in-law!

You are like a soft breeze in a warm summer day – gentle and cool. Wonderful bday, sister in law!

Your brother and I, would like you to have a great and fruitful life because we both care about you.

Most of the people I know do not get along with their in-laws, but not in my case! Happy bday, sis!

When I married your brother, life has thrown in a wonderful gift in the package! That is you, my sister-in-law!

The memories and joy that you have brought to our daughter’s life is priceless. When she grows up, I would want her to be like her auntie – beautiful and strong.
