STYLEGAGASTYLEGAGA Women's Casual Knee High Socks

Hi are these nice and thick or thin where your skin makes them change the color to not so white?

How many pair of sock come with the order!??

Will these be too long for short legs (5'0) and small feet (size 5)?

For $16.90 how many pairs are there? Some say 3, some say 5. Please help
