How can I slim down muscular calves and thighs without becoming too thin in my upper body?

I've always been active and was even a professional dancer, but my understanding of exercise science is limited. Regardless of my weight (ranging between 100-130 lbs at 5'5"), my calves and thighs have always appeared disproportionately large. My calves, in particular, are naturally muscular—I often need custom-made boots when my overall muscle mass increases. Additionally, my thighs and glutes store both muscle and fat very easily.

I suspect this is partly due to genetics and my dance background, but is there any effective way to slim down my legs without drastically reducing my upper-body size? I know spot reduction isn’t possible, but simply creating a calorie deficit doesn't seem to change my proportions—the lower half of my body remains noticeably larger than my upper half. Any insights or strategies would be greatly appreciated!
