Gorgeous Vintage Ralph Lauren "Chambray" Standard Pillow Case. This item was made in the USA sometime prior to 1987-1988,when most domestic production of Ralph Lauren ceased. This one is marked irregular,but I honestly can not tell you what the flaws are,other than the manner in which the label is sewn in.  The fabric does have a few scattered dots of darker blue. I believe it is simply the nature of this fabric. I haven't noticed any damage.This fabric is on the lighter side of powder blue. It will arrive at your home freshly laundered.
