Hi Holly,

Thanks for the question.

You said:

1. Do I have to be Catholic to be married in a Catholic Church?
   <No, but read the first posting below.>
2. What does it take to become Catholic?
   <Check the FAQ, the second posting below.>
3. What is proper dress attire for a woman's wedding dress in a Catholic Church?

To my knowledge there is no proper dress attire for a woman's wedding dress in the Church.

For attendance at Sunday Mass, proper dress would be something that is modest, unpretentious, and becoming for a woman.

These postings should answer questions 1 and 2, if not, just come back with some follow-up questions:

1. Can I marry a non-Catholic in the Catholic Church and how do I ask her to convert to Catholicism?
2. How does one become a Catholic?

Many answers to questions like these are in our searchable knowledge base.
Try next time for a quick answer!

I hope this helps,

Mike
