total mess up!

How can sellers be sooooo foolish? The colors do not display correctly, size charts are messed! Is it SOOOO DIFFICULT to describe your product correctly?!!! If you don't know exactly about the sizes of your products, then just simply take a picture of the back side of its package and upload here!I'm just really angry with such kinds of sellers! Isn't it evident that it is so silly to sell products like this?Such messy things do not attract customers!I am now in a search for about 10 pairs of tights, but definitely not buying it here, though quality seems to be ok! I just don't want to be fooled about sizes and later spend my precious time for cancelling order, changing products, etc..
