This is also an unrealistic expectation people have and I don’t really care what some Glute guy says, you will not simply grow your Glutes and that is it. All of the exercises to grow your Glutes also grow your legs. So if your Glutes will get bigger, so will your Hamstrings and your Quadriceps. There is literally only one singular exercise that works only the Glutes, or should I say one Glute Muscle and that is the Glute Medius which is at the top of your hip. Hip abductions will isolate the Glute Medius but in order to build a great set of Glutes you need to work all of your muscles of the Glutes, not just the Medius. You feel me? So no you wont have skinny legs and a large butt. It doesn’t work that way. The only way this happens is through surgery.
