I own a Maxcita psycho II straitjacket and boot set. Started wearing diapers after a back injury a few years back. It's a well made jacket with twin crotch straps. I wear it as regularly as I can with pull up diapers and a Leotard as it's easier to slide on and off on your own. Usually I'm on my own which means I can't put it on completely as it's impossible to get out of so leave the collar, shoulder and chest belts undone and just tighten the waist and hips belt as tight as possible. Before putting it on, I fold the arms through the tummy and side loops and belt them together, do the same with the upper arm belt. tighten the crotch strap belts then slide one arm in all the way to my shoulder, then with the help of a hook on the wall through the shoulder D rings I can slide the other arm in then pull the jacket onto my shoulders. On the odd occasion I have help but only for an hour or two as no one in my own family know about the diapers or the straitjacket. To be honest.... I'm too scared to tell them. I'd love to have help from someone who has space and time so I could wear it for long periods of time as it's so comfortable when it's on.
