I would call this a craft or utility apron. If you belong to Sam's club, they have pretty inexpensive white chef's aprons. What I have done is fold the bottom to the front and make vertical seams to hold different items. I made these for friends and used my embroidery machine to add a monogram on the bib and a couple small motifs on the pockets. they came out really cute.
