This is a great replacement for the plastic shirts that come with shirts as most of the time the plastic shirts are too thin and my collar still creases. It's nice to have three different lengths but I've found that most of my shirts are the shortest length and sometimes I have a shirt that I use in medium length, I don't think I've had a shirt that was the longest. will work with. Having a plastic case is great too as I've only ever kept the plastic case in a mess on my dresser.
