Just what I was looking for...
I was looking for a hair clipping smock that would fit over a lightly insulated jacket for outdoor haircuts in Oregon in winter, and this is just the ticket.  I normally wear a size 14/XL, and this is sufficiently roomy and comfortable to wear either with or without a jacket.  The snaps fasten easily, so no concerns there.  Couldn’t be happier.
