Soft, but too short for my long legs
Size: 10, Color: Basic Pack
These are soft, but much too short in the legs, so that I have to continuously pull the legs back down out of the crease between my upper thighs where it creeps up into the crease btwn the thigh and stomach. If they were about 4-5" longer they would be a 5☆ rating for me.

NOT COTTON PANTIES!
Size: XX-Large, Color: Multi Colored
The site said the panties are 100% cotton. LIE! They are some horrible stretchy material that is most likely a petroleum product. ie polyester or some man-made horrible material. The colors described on the site were very light pastels. LIE! The colors were hardly bright- dull, ugly muted brownish colors. UGLY! Don't believe the site. Don't buy these panties if you adore cotton!!!! Caveat Emptor.
