I had to go back to revise my review because I just pulled the dress that Nikki altered for me, and literally everything she did came undone. I've only worn this dress once, for an event in 2014. I have not touched the dress since.
Not sure what type of thread she used, but she obviously didn't do a very good job at tacking her seams down. What a complete waste of money, I do not recommend going to this lady.
