Gaining Weight In Thighs

Hi everyone! I want to gain weight (only in my thighs though). I'm 24, 5'6 and 110 pounds. I've been petite all my life. I would like to gain 5-10 pounds. I workout now to maintain my flat stomach and curvy butt (I got lucky lol). I really love my shape but I wouldn't mind putting on a little weight in my thighs. I've been doing squats and leg presses at the gym, is that a good idea? Any other suggestions? Thanks!
