Below is a quote from another thread. It is from Arkady that provided the pattern that is used in his/her wonderful budget flight suit. Please note whatever you use it will need to be modified. Some things to note is where the seams are at on the sleeves (Up versus down), the pockets on the front (I suggest putting those on BEFORE you stitch the two pant halves together, the shin pockets, and finally the boot straps and other parts. Also make the determination if you are going to integrate the neck seal in the flight suit vest or stand alone. etc.. I ended up using a pants pattern and "eyeballed" the top from pictures on the net and I DO NOT suggest doing it the way I did. Good luck. Check the link below Credit for it goes to Arkady!
