I bought two pairs of these, one in black and the other in heather gray. The black seem very thin and silky soft almost like nylons and are shiny kind of see through but not. The heather gray is thicker more cotton seem more durable.  BOTH pairs however have pills in the inner thighs after 1 days use,  they were not as wide at the bottom as I expected either,  I invisioned more of a bell bottom type of look. The one plus they are both comfortable but  not expecting them to last.
