Flight Suit as Base

Instead of starting from scratch I decided to build upon something I already had. A flight suit. This was going to be a big costume, and it was going to be very warm since it would be almost 100% foam. I wanted to make sure it wasn’t skin tight so I decided on using clothing that was bulky, and this is important. Luckily I had an old flight suit that you can get from any online military surplus store to use. It’s nice because the flight suit is a one-piece but I’m sure you could start with an old pair of sweat pants/shirt if you needed.
