I need help to buy my sister wedding dress

A little story about us
The difference between us is 2 years, I am 27 years old, she was 29. A few years ago we were not only brothers, but also the best friends. That is until 2008 when our dear father went to heaven. Then broke it between us. I remember my father's funeral we argued very bad. It was our first fight, and the last time I saw my sister. Since then I went to Spain and I have not kept in touch with her.
This quarrel of us affected me greatly.

What do I do now?
Now I want to surprise her. I know she is pregnant and should give birth this month.
In early August will be the wedding, so I talked to my future brother in law about it, and I said I'll buy her wedding dress, he should give me just after birth measures to order the dress. I will send the dress by my mother who is here in spain with me. Surprise want to do on your wedding day when the bride to be led to the altar. that it is not expected to be present at her wedding because she tried to call me several times and I did not answer the phone.
