There are two lengths of scapulars I have seen (worn around the neck). The shorter one is for sports. Really there are 18 approved scapulars, but it is hard to find all of them now. Also there are cords that can be worn around the waist, and also badges that are pinned on, or just hang or a string.
Because scapulars hang around the neck with one part in front and one in back, you have to adjust them sometimes, because the back part will pop up sometimes. They are a little itchy because they are wool, but that is a reminder.
I wear the five fold scapular that has 5 wool scapulars (really 7 devotions) in it and small (aluminum) crucifix and St. Benedict medal hanging on the front strings.
