Here's how my partner has categorized the project.

Conforming or hybrid figures:
Leather bomber jacket  (A2) or fabric bomber jacket (B-10)
Leather and/or white gloves
Parachute pack - I think this would be the hardest to make conform properly.  Maybe just a parented prop that inherits bends?
Mae West
Leather boots
Pants (none pictured, but that'd be a good idea)

Parented props
Helmet with air mask (needs easy pose tubing)
Goggles
Cap (with insignia)
Scarf
