How to slim waist & thighs but build booty???

??? • sin miedo

Currently 28 waist, 39 booty and 23 thighs. Goal is 26 waist, 40 booty and 21-22 thighs. Any advice on reducing waist and thighs while gaining booty? My thighs in particular make me feel insecure about how I look cos I'm only 5'4 and I live in a place (Asia) where every girl is size 0-2 😭
