How can I get a smaller waist?

So I have a round butt thanks to my squats and leg lifts... My mom and sisters judged my butt with the chart and all agreed I have a round butt, BUT (pun so intended) I have the upper body of the square person shown below... My mom said all I needed now was to make my waist smaller and this is one of my goals.
i weigh 113 llbs and I am 5'... What exercises or things would you all recommend so I can get a nice small waist :)? I've been doing the bicycle style exercise in which the opposite elbow touches the opposite knee but I would like to know if I should waist train and if they've gotten results from that or another exercise :) thanks everyone !
