where are the size measurment instructions? it says measure 6 inches above and below knee, but it doesnt have a size chart telling you which ... ?

The size chart is among the product photos. Not super helpful.

Are these sleeves, size large, black and gray (as pictured) or all black? if black and gray (as pictured) i will order 2.

They are gray and black as pictured.

My thigh measures 23 1/2 do I need to buy a large or xlarge?

Are you wanting more compression or is it an under brace sleeve? I would go with the large.

I have a medium/large brace and the sleeve that is included. I need a larger sleeve. What comes with it, medium or large?

I have a large brace and bought an additonal extra large sleeve because the large was small.
