The slip for sale has no tag, but I actually have 3 of these vintage slips that are identical in size and appearance. The second one has a tag that allows me to identify and size this one.  There are no holes or tears.  The midriff is spandex to shape the area and shows some puckering, more so in the back, from being worn. It is very stretchy. Tried to show light discoloration on the lower front but could not get a good picture.  It is not a dark stain just a difference like something splattered in that area.
