There are many different kids apron forms depending on the purpose of the
kids apron. A basic distinction is between kids waist aprons which cover the body
from the waist down and a kids bib apron which also covers the upper part of
the body.
A kids apron is usually held in place by two strips of fabric
that are tied in the back. A kids bib apron may either have a strap in
around the neck (perhaps the most widespread use today), or shoulder
straps that criss-cross in the back and attach to the waistband. The
advantage of the former design is that it makes it especially simple to
put on the kids bib aprons. The advantage of the shoulder strap design is
that it makes the kids aprons more comfortable to wear.
