How fast will thiss work? how long tilli see a difference?

Well i want to get thinner thighs. Really my inner thighs mainly. I have done lots of exercises for my thighs and i am a dancer so i have muscly legs but i still want to have thinner thighs. Or at least to tone them up. Most of my leg is muscle. But still i wanna be more comfortable in shorts :/ at least for myself cause i don't think i have good legs even if my mom or friends say it. I want it for myself. So i want to know what exercises should i do and how quickly do they work? I eat healthy and drink lots of water too. I'm a dancer and i do want to be thin.
