7BigStar Women's Cotton Dress Socks - 4 Pack L/M - Solid Striped Crew Black Brown Blue Grey Beige Khaki Olive Green

Is this package four socks, or four pairs of socks?

if i get beige socks to wear with flats and pants will it be noticable that i am wearing socks? i am trying to disguise them

I wear a size 7 shoe.. size I should order?

Can I pick the colors I need?
