Go to any military surplus store and buy a winter nomex flight suit. Contrary to what others have said, they certainly are warm, and quite comfortable, and yes, they are fire resistant. Ultimately they will melt, and yes, they will burn, but won't contiue to burn after the heat source is removed excepting excessive temps...in which case you're already past help.
I believe the designation is CWU-64 (cold weather uniform). These are much thicker than the typical flight suit that others here might be considering.
Also, contrary to popular opinion, while the thin nomex suits won't hold up to continuous flame, they do provide a measure of protection against a flash fire, and wearing them is worth the discomfort. My helmet is uncomfortable, too...I'm bathed in sweat after a hot day of flying under it, but it's a required, important piece of equipment, and I wouldn't fly without the nomex or the helmet where it's required.
As others have stated, barring the availability of fire resistant arimid fibre suits, cotton is your best bet. Cotton burns more readily, but it's better than synthetics that include polycotton.
