I am 6'4....will these even go above my knees?

My brother is about 6'2, 6'3, and they went WAY over his knee (I just made him try them on lol).They were about under his butt, if I'm not mistaken. They will stretch out though, to accommodate the size

I am 5 foot 7 and 95lbs would these that my skinny legs ?

Depends on how your legs are shaped, could always get some garter belts

Can you remove the bows?

They are sewed on, but easily snipped off with a pointy pair of scissors. That way you can always sew them back on, too, if you wish. OR you can use the bow on something else instead.

5'8, 135lb. Should i order a plus size or regular?

I think because of your weight, that the regular would most likely work the best for you. The plus size on me, being 5'8 & having thicker thighs, can stretch way up to mid thigh.
