We recently bought 2 sets of these apron/chef hat outfits and have 6 outfits left.  They are brand new, never worn, still folded in the package.  The colors we have left which are included in this listing are 1 white, 1 brown, 1 burgundy, 1 orange and 2 green. 

They are adjustable around the neck, tie in the back, and have two pockets in the front.  The hat has an elastic strip in the back for flexibility.

They are made of polyester, and so, are machine washable.  Dimensions are shown in the picture.  They listed them as appropriate for 6-13 year olds, but they are a little small for a typical 13 year old; more likely 11 or 12 year olds as the maximum.

We bought these for kids' baking lessons, but they could be used for art class or anything similar.
