I have some shoes that thin socks feel to tight for the shoes.  I decided to purchase pantyhose but I didn't want the restriction of having full hoses on all day.  I started looking for the Knee Hi version and was floored by the costs of them. I found these on amazon for roughly .60 a pair.  The other ones I looked at cost about 2.50 a pair.  I have been able to wash these and get multiple uses out of them.  This was a great buy for me.  The colors are limited though.  The nude are too light and the suntan are too dark but what do you expect for .60 cents?
