She cut my wedding dress smells like smoke.

This is a rant , I love my dress, One of my so called friends who I was going to ask to be in my bridal party, Had no place to go with her 2 girls so I let her stay with us.rent free so she could get her life together. she is the gal in the picture with me in my wedding dress. I left my dress in her room so my fiancé wouldn't be tempted to look. she took use of my sons room. With strict instructions to not smoke in the house. I am highly sensitive to tobacco and weed smoke. So she left we had to have her evicted due to her neglecting her kids and hitting on my fiancé. my fiance never gave in to her advances but he told me that she was flirting and it made him uncomfortable. so she is gone thank gosh. I was cleaning up her room and it smelled like smoke. I was fuming I had bought a garment bag with my dress. and thought it would protect it. nope and I was looking at my dress and she had cut some of the buttons off. Who freaking does this. can I get my buttons back on? and how do you get cigarettes' smoke out of a dress. I am in tears my beautiful 3,000 dress that I got on sale is ruined. the fabrics is lace and tulle. do I have a right to be mad?
