Hey all its been a while since I have been on here but my fortunes have changed and I am starting over on everything. I had a decent pack that I made years ago that my Ex wife destroyed, therefore as I said I am starting over and this time I am going to do everything the right way (pack build etc), my question is this: my Fiance wants to get involved with this as she is a big GBF as well and so with the release of the new movie I am going to make her a pack like theirs however I cannot seem to find the flight suits they wear anywhere online, my hopes is that someone can point me in the right direction! Sorry for the long post. 
I came across this on Amazon while looking at reflective tape options https://www.amazon.com/Stail-Shop-Ghostbusters-Jumpsuits-Cosplay/dp/B01HRPG5K4/ref=pd_rhf_dp_p_img_1?ie=UTF8&refRID=WS5SSNVHSKXBQYM088Y0. And if you scroll down the page there are other options too
Crazy expensive for a jumpsuit, but that looks pretty solid!
