JoulliWomen's Knee High Athletic Socks Stripe Tube Outdoor Sport Socks 1-3 Pairs

Could I wear these over skinny jeans?

What is the length of these?

How do these wash? I have found that many socks that are cotton will attract lint or get full of pills after a few launderings. How do these hold up?

If it shows three colors can I get all of the same color?
