Some very interesting views – I cannot help but agree with the apparel for women!
I also agree with the flying suit arguments. As a tail dragging performance bi-plane flyer, I feel I am at most risk in two areas.
Tearing off the wings during aeros – for which a chute is my backstop. An accident on landing which renders me unconscious and an ensuing fire. Therefore helmet and fire resistant flight suit and are my choice of apparel.
However, on those rare hot summer days, t-shirt and shorts is appealing!
