I purchased these cotton half slips because a friend/colleague of mine said that she found cotton half slips very comfortable under her nursing uniform when she wore a skirt or a dress. I often wear skirts and those nylon jobs just tend to ride up so that by the end of the day, it is more like a hula hoop that a slip. Anyway, these things are hard to find and Amazon listed these as made in the good old USA. I purchased two in my usual size but when I got then, I found they were running small. Although I could get them on, I just felt that were too snug to really be comfortable so I had to send them back. In addition to running small, the cloth is very thin and the elastic waist band is minuscule. I almost decided just to get a refund but then decided to take a chance and get a size larger hoping that they will wear better than I think they will. Anyway, I had to pay an additional $5.95 to get the slips sent back to the company (located in Massachusetts) and then resent back to me. It is yet undetermined how these will last. I have clinical coming up in a couple of weeks and will be wearing these two days a week for 8 weeks. That should prove how they hold up. So stayed tuned for an update.
