Makeup Artist not getting back to me

I am having a Halloween Themed Co-Ed bridal shower and I am dressing up as Emily from the Corpse Bride. I hired a woman who does the whole Halloween makeup a few months ago and gave her a deposit and then she told me to send her pictures of what I wanted so I did...and I haven't heard from her since. I have messaged her to ask her questions about the makeup (to see if the blue makeup/paint will stain my skin, etc) and asked if she received the pics and to set up a time for her to do the makeup before the party. The party isn't until the Oct 23rd so IDK if maybe its still too early for her to get back to me but now I'm worried because she has completely ghosted me. I hired her way back in July because I like to get things done and settled in advance and it's starting to worry me that she hasn't replied to me since. Should I wait a few more days or should I message her one more time to see what is going on/get my money back and hopefully find someone else before its too late.
